Oh yeah you can throw mines around. And what then? You spew 3k credits worth of mines and the starbase will still be spitting doom upon your fleet from behind them or circle the mines. Besides, he can do the same to you (we're talking vasari vs vasari). Moreover, one scout and the starbase will clear mines faster than a dozen flak frigs.

Not really a stable strategy.

Lich, you have just spent about 50000 credits in that battle.
Mines, Marauder, Vulkoras, Carriers, Egg and whatnot.
Pointing out that if you do EVERYTHING then that single starbase is gonna die is not a valid point. You can't do EVERYTHING, otherwise the game is over before you are even halfway prepared.

Most of your initial arguments are off track as well. What makes you think that you can wipe his fleet easily? What makes you think that, regardless of having a floating Starbase and tactical sructures and whatever, he will actually rush his inferior fleet into your armadah of doom?
The defender should keep his fleet near his starbase. There's only one moment when he should rush you and it is when you're trying to build a starbase. Your starbase can't run away from his, so you can't do all that dancing you talked about.
Mind that Vasari too have Enforced Loyalty (aux government equivalent).

Your post is all about imagination unless you post a replay how a non-retardedly placed and defended starbase goes down to a clever use of your 'tactics'. You just kept throwing Ace after Ace from your sleeves as if you had a card factory in there.
Fleets are not composed of EVERYTHING because you would require dozens of thousands of credits to research that EVERYTHING. It's better to have more ships than a handful of ships and all research done. Research alone won't save you.

So, summing it up, your post in purely theoretical.

So all you can do in this match is use Kosturas (which are foultardedly expensive) and brute force (aka SPAM).

Being the only matchup that gives the attacker only these two options (none of which being doable until very end game), it is screwed.

1] LRFs aren't safe out of Orky's attack range. Orky can move. If you want to keep retreating your LRFs, you are wasting a lot of firepower on dancing.
2] Nano disassembler loses on its effectiveness with every defensive upgrade on the starbase. Insane armor makes the -6 debuff a lot less effective than when used against low armor targets. 30dmg/sec is reduced by armor too, which will still be way over 10 points even with 6 substracted.
3] He has a fleet as well, it's not just a big flying brick that you're fighting. Overseers will heal his starbase, Subverters will turn of your spamfleet now and again. His HCs will focus your own and kill them off one by one while you're trying to reduce the huge pile of hit points on the starbase.

Vasari have nothing that excels at killing structures/starbases other than their own starbase, which in this scenario is offensively useless (cause the defending one will wipe it)

Ok, so we agreed that we would have a superior fleet. Well, if they did spend an upgrade on Auxiliary Government, that is one less upgrade on something else. Yes, my post was theoretical, but we are talking about a Starbase that is fully upgraded and is supposedly at a point where you can't just leave it for last. On the research topic...what have we researched...carriers, fleet upgrades, ruiner, Starbase deployment. Not really asking for that much.

Now then, though it is a pain to kill that Starbase, it is certainly doable. Now this is assuming you have accumulated that fleet over the entire course of the game so a large fleet isn't unreasonable. I hope that I can make the assumption that you have the superior or equal econ/territory given that your fleet will wipe out his fleet anywhere else.

Ok, so his fleet is going to stick with his Starbase, that's fine. If that is the case, that is fine. Use your ships to attack his tactical/civilian structures--particularly the hangers and regen bays. While running around, you either force him to outrun his Starbase or force him to lag behind with his Starbase. You can drop mines while you are at it.  Credits providing, you can build your own Starbase in the minefield you lay down--hopefully on the opposite side of the Grav Well. If you are lucky, his fleet will leave the Starbase and go attack there. You are ahead of them since you are running from the Starbase so you can go cut them off. Get his Starbase snagged in behind some structure too if you can. I'm not sure...but a Maruader might help your Starbase move faster too. If you have money left, more mines for the pursuing Starbase/fleet. All in all, yes, more theoretical stuff, but maybe you can pull it off.

Just so I am on the same page, are we saying that Vasari vs Vasari is no good because they don't have an Anti-Structure cruiser. Therefore, they need an anti-structure cruiser? Or since Vasari are about mobility, they don't need one but don't do squat against that fortified position.

Out of curiousity, how can you not attack another front? Even if their fleet tries to attack your now exposed front, you can Phase Gate right back to it. Yes, your Marauder will be left alone...but his fleet is elsewhere and you can jump back in later. Heck you can even drop a Starbase on that vulnerable position. With a PJI on your front, you can wipe out a lot of his fleet if he tries to retreat. If you have him cornered or he has a fully upgraded Starbase on every planet. Well, he has already lost cuz he probably has very few planets and a pitiful fleet. He isn't going to be able to get anywhere and you can eventually take him out. This is assuming he isn't whooping you so badly that he has nothing better to spend credits on .

I read most of the first page (before it got completely side tracked) and the OP.

I've encountered a Vasari Starbase (granted, with lvl 2 or 3 defense, not 4) and an enemy fleet before as Vasari and I didn't have a great deal of trouble killing it (though it coset me) using similiar tactics to what is already been said. I wear the enemy fleet down with lots of ships, reinforcing as fast as I can, and when his fleet is down, focus-fire on the base. With a frontal sheild, I flank it.

I know it's not what you wanted to hear, but that is how I take out Vasari starbases as Vasari. One thing to keep in mind though is that if he's Vasari, he is also effected by the same limitations. He has no anti-starbase weapons outside of his own base as well.

There really should be an anti-stucture ship or ability for the Vasari..... perhaps allowing phasic cloaking (I think that's it, what the scout has for an upgrade) to be how Vasari starbases are built in hostile systems. With other ships augmenting it (repair and such) once it's built, it might make it viable, or even have additional migrators help build it's defenses and weapons quicker. [EDIT] Or perhaps allowing a starbase to be upgraded with a one time phase jump drive!

Sticking to the thread topic...as mentioned already...use bombers and kite the carriers.

This is against AI. They are pretty oblivious to Phase Gates and PJI's.They will also charge recklessly into your fleet or retreat. They also fall pretty easily for mines.

WTH are you talking about? This is about Vas vs Vas, what's Transcencia got to do with it?

No; we can apparently expect any N3rull to turn any Vasari-Vasari thread into another duplicate of his previous rantings while he presumes that Vasari should ignore its strategic advantage of mobility and instead attempt to duplicate other faction's strengths into bludgeoning choke points.

There are *no* choke points against a sufficiently teched Vasari in intrasystem warfare.   This is not something that either of the other factions can say... ever.  So yes, a single fortified system can be expensive to take, but the expense required to defend it isn't defending anywhere else, and isn't particularly important to power projection in the late game (considering that Vasari don't have to have any nearby territory at all to launch an attack)... and a single fortified system can't sustain the economy necessary to replace losses from attrition.  So that leaves either counterattacks (possibly resulting in mutual devastation system-wide, and elsewhere -- making the bases largely irrelevant other than as PS nodes) or attempts to corner the attackers (which can be tricky depending on what they brought with them, and how good the attacker is at arranging multiple fleets and micromanaging -- considering that neither attacker nor defender can change orders during the possibly long phase jumps, good guesswork would be crucial).

TEC or Advent *needs* ways to knock out fortified systems, because they don't really have a choice if the map has chokepoints -- they have to go through if they're going to go at all.  Vasari can hit elsewhere in order to force a more dispersed defense and to make the eventual necessary attrition more acceptable.  Why else would you think the Kostura got the Phase Gate ability?

Lastly, the Vasari ability to project power around the map with Kostura/Antorak/PS is more endgame than ANY OTHER TACTIC that could be mentioned by ANYONE about ANY RACE when they have a fortified chokepoint problem.

TEC, Advent and even Vasari in any different matchup require only 2-4 Military labs to establish a decent anti-starbase tactic.
If Kostura is to be mentioned as a mechanic parallel to the TECs direct assault, then Kostura should
- be Tech-level 4 instead of 8, 
- cost 2000 to deploy instead of 8k and
- not require you to have a lvl6 most-useless-cap-in-vasari-arsenal(tm) or Level 5 imperial tech done.

Can't you understand the deal? Vasari are not the most mobile race of all ever since they get to tech level 4, when other races get their starbase busting tricks. Vasari become uber mobile a dozen times later in the game and need a lot more money spent to get to that point.

OR, maybe torpedo cruisers should also require Tech-level 8 research?
I mean, come on - you said yourself that TEC/Advent have to bust through, while Vasari can go around. Up until Vasari get Phase Stabz and Kostura, they are no more mobile than any other race.
So why, oh why, should everyone else be given their tools a dozen tech levels earlier?
hah hah hah?
