Subversion isn't the problem imo. They buffed it a long time ago. Starts off ok. Ends up being brutal if you ever get it to level 3. One of the things people don't realize about subversion is how long it lasts (a damn long time).
I dunno how you should be asking from the support class. Between the Rapture (I think that's the advent support cap), Marauder, and Dunov, the abilities they bring are all great, but they're not direct.....they're indirect support.
The marauder provides a counter to MB, the abilitiy to BYPASS phase jump inhibitors & outrun your enemy to get a jump start at attacking stuff behind enemy lines, and also gives like a 5 minute delay to planets in ship production and construction THAT CAN STACK. You have no idea how much you'll frustrate someone if his planet is building with a 300% red multiplier (he constructs at roughly 1/4 his normal rate). Great for TEC players abusing repair bays.
Still, the cap doesn't stand alone. Needs fleet to support it. Overall, great ship though.
Since we're down to discussing cap ships again, I just have to respond here.
In my opinion, it is a very important difference between an ability A that is powerful and sometimes useful and ability B that is awesome but useful only once every fifteenth game.
1] Shield restore. Powerful support ability that you will find a use for in any game you play as long as there is a second ship next to the Dunov.
2] EMP charge. Works against all cap ships, takes out antimatter, ceases channeling, disables abilities, is AOE, destroys shields. A hundred uses for it in any game you play, as long as the enemy uses any abilities at all ( = always).
3] Magnetize. Fouls up the enemy's usage of abilities and wipes his strikecraft. Awesome. Always.
4] Flux Field. Awesome for any cap that wants to spam something. Akkan would want to spam ion bolts on enemy caps. Marza would like to spam rad bombs. Kol would like to spam everything. Always useful, even if being a support ability.
1] Vertigo. Useful in any battle.
2] Vengeance. Useful in any losing battle.
3] Concentration. Useful in any winning battle (lol?).
4] Domination. roflmao.
1] Phase out hull. Useful when you want to disable an enemy ship's channeling... and? Yes, there is a dozen more uses for it, but SERIOUSLY, how often does that crap happen? Besides, it is a two edged sword. Yes it is spammable, but the enemy is immune. So are your ships. Immune, but useless. The tactical potential is incredible. Usefulness is almost nil.
2] Distort Gravity. Makes ships move faster. And? Like, I mean, wow, holy moly. My ships fly faster, yay. Ignore pji's yay.
Now seriously, thanks to the pathfinding issues that makes ships change their jump-out point when they get dist. gravity, the ships start maneuvering more than they should and the effect is almost nullified cause dist. gravity does NOT increase ship turning speed. Besides, fleets always fly as fast at the slowest ship, meaning the Marauder, which doesn't become a real hot rod at all.
3] Subversion. yaaaa. Awesome.
Slows construction? Great. He won't build turrets. Question - why would you NOT kill his constructors the moment you see him starting any construction?
Slows ship production? Great. You really believe he does not have factories in nearby gravwells? That's the usual scenario anyway - a river of ships jumping out from his nearby planets until either you wipe everything except the ships that just entered or he wiped you like that.
Gives 5 minutes of vision? Awesome! ... or is it?
4] Phase Stabilizer. Yay! Needs you to have phase stabilizers researched yourself, built and fleets ready to get jumped. Very, very, VERY situational.
So, all in all, I do NOT believe one support cap is equal to another.
Some are useful in any game.
The other is a gadget.
edit. all the above was typed in a hurry so not all tiniest aspects of the mentioned abilities are addressed, but the point is made. A dunov or a rapture both can do something useful in any battle and we all know that battles are where the game is decided (well, you do have to lose your fleet before you lose the game, unless you're sabotaging yourself, did something very silly or are totally drunk ).
Antorak can do a few things that might never have a chance to meet the situations they're made to counter, cause what they're made to counter hardly ever happens.
I personally do surrender if I'm the last person on my team.
Let's play 1v1 lol.
