Titan + Titan foundry + 4 required techs + 2 capital crew techs + 1 fleet supply tech

Quite expensive, especially since the only way you can make one better is through combat...SBs, meanwhile don't require any risk or combat to upgrade, just money...

I assume you mean anti-structure frigates (like ogrovs)...problem is that Orky can chase them and kill them (something other SB can't do)...you need an assine amount of ogrovs and have to catch the Orky in a really bad spot in order to actually kill a fully upgraded Orky...

Additionally, ogrovs serve only one purpose: SB killing...investing in them presents a huge opportunity cost - yeah, you may kill the Orky but now what? The enemy will walk over you with their fleet because you have none...ogrovs are expensive and take up lots of fleet supply...they have their place but they are by no means a viable counter against jumping orkies...

Bombers in general are more useful...TEC and Advent players still prefer to use bombers over anti-structure ships, mainly because they are actually useful in fleet battles as well...so, Vasari aren't really at a massive disadvantage there...plus, you can still bring in a migrator and build an SB there that can then move in to attack...can be tricky at times but the Orky and the tricks you can do with it more than makes up for a lack of anti-structure ships...

There are several things you are forgetting or haven't properly addressed...fleets require factories, which take up logistic slots that otherwise could go to trade ports or labs (read: money)...SBs require no fleet supply, allowing greater economic development than someone with a large fleet could obtain....jumping Orkies can be "stockpiled"...you can put one on each planet, and just bring them in as you lose them...you don't have "spare" fleets, you have to remake those from scratch ever time they are killed...

I'm not trying to be mean here, but if you really don't think VR are OP with jumping orkies, then you haven't played against someone who can use them even remotely well...any decent eco player can just throw one of these to each of their frontliners with little skilll and single handedly decide the game...

1. Economy is almost never a problem, ever.

2. Thats kind of the rule.. I don't see how that is relevant.

3. Its the combination of Titan + Orky, your siege frigates will just waste resources and only the TEC's are actually cost effective.

4. Its the combination of Titan + Orky

5. Its the combination of Titan + Orky, orky also does damage because of its weapons banks.

6. no.

7. Twin Starbases is pretty broke to with red button, but its situationally broken. TAR isn't that good to be honest, its a trade off, also why include their titan if you didn't include the Vasari-Rebels.  Don't even try to call the Advent Loyalist good. Advent Rebels are pretty broke once they get there titan + guardians/Defense Vessels out. The Vasari Loyalist are balanced however. Yes they have there perks but the point is Orky + titan is broke theres no point in comparing it to other races.

The only feasible  solution is to make jumping orkies only able to jump in friendly gravity wells(Maybe suns/Pirate Bases too). It also fits the Rebel theme of defense.

Ok I see the points with the bombers etc. I don't play much ICO and V AI I tend to be a little heavy on fighters to maintain air superiority. And I disregarded the relative difficulty in unlocking the Titan v the Starbase. I do have to say the Starbase is still a much more expensive purchase. I also wasn't thinking much about the eco side of things and the upkeep income modifier. I did consider the stockpiling of starbases but even in the biggest maps I have found that that is a huge drain on resources but often its because I am building 7 or 8 at once trying to establish a defensive perimeter. I never thought much about logistics slots beside research. I am not trying to be antagonistic or anything here. I don't play online much because of an issue with my ISP where they reconnect my service every couple of hours (and boot me from whatever I am doing.) and so I end up playing lan with people who like me mostly fight an often disappointing AI. So you aren't being mean just enlightening me.

Indeed. This would be the one thing that would help the most, especially if it took at least two upgrades as that would diminish a jumping orkies' combat power.

Make it a 2 level starbase upgrade, and they need to cost fleet supply.

Its OP because its a very powerful unit that does not cost any fleet supply.
