It was the ai of course, but this still has merit.
I killed four capital ships with a marauder and seven(four left when I was done too) skirmishers. Two dunov's, a sova, and a kol.

It's amazing what you can do when the big guys don't get to fire till their escorts are dead, and then only get to shoot at you till you want to leave, at which point you blast out of there faster than their frigates can move, your entire fleet easily retreating. Killed the poor bastards planet twice while doing it, and built a secondary fleet while keeping the ai thinned out to just a few frigates the entire time. Vasari can run away from anything, and they can chase down anything too. Some of you(multianna for instance) really need to think outside of the box a little. These guys are the kings of mobility, even before phase gates. I'm still pretty sure I'd lose to myself, no shield regen abilities in the bunch, and only the carrier can actively repair other ships on the move to real effect. They are not freebees though, they are godlike tactical strikes that can get in, get out, get back in, get out again, rinse, repeat... Phase gates are game over, they don't become balanced with them, they go from a little weak to god almighty accidentally stepping on a bug.
And ignore the frigging pirates already and look at the maps a little.

Both ai sides are getting creamed by them, the TEC are just getting creamed a little less. They've seriously cut back on the defensive structures, so they get floored whenever there isn't a capital ship close enough to defend. The pirate fleets are almost always larger than the ai fleets are. Going squishy by pirates because there isn't a single turret, repair platform or hanger in the entire galaxy does not make a side weak.
