Stilakus Subverter - effective counters?
Let me start by saying that, in the hands of the CPU, the Stilakus Subverter is a *pain* to fight against - pretty much nullifying my entire fleet when faced in numbers. I have the feeling that they would be less effective (relative to other solutions) when playing against a human opponent, but for the purposes of this thread lets assume we're talking just about AI-controlled ships.
So - can anyone give me any effective counters for the Subverter? I *could* build an assload of light carriers, I suppose, but when facing a fleet with 50+ carriers and 40+ subverters my fighters are pretty much engaged with keeping fighters/bombers off my back. Capital ships are not completely disabled, and are good for engaging a small number of the beasts, but against a large swarm they just don't have enough firepower to clear them out quickly enough to avoid my fleet being decimated, unless I have all 16 in one place.
I play as TEC, and when I face a vasari fleet I always take out the subverters first, but like I say, with large swarms it becomes impossible to destroy them all without getting frozen out of existence. I favour 'blob' fleets of heavy cruisers (which probably doesn't help the matter), backed by capital-ship carriers, but I have no problem mixing it up a bit if the situation requires. Is there any 'area-of-effect' counter available? As it stands the subverters seem cripplingly powerful.
(As an aside, I play against multiple AI opponents all 'ganged up' against me, so destroying/damaging enemy fleets quickly is important. Losses can be replaced, but lost time cannot)
