Appearently you dont know the full ability. WHile it does make your capital ships rather dorment, it also causes everything to stop focus firing on it, because if little more than a small amount of damage is taken, the crew snap out of it. (explosions will tend to wake people up and stuff). It is not the strongest of the disables... but its the only disable that the ai can seem to use properly.
75 kodiaks? thats more like it. trust me, those capital ships make a negligible contribution to your dps compared to 75 kodiaks. You sould be poppin those cap ships no problem. expecially if your using your ceilos well. :-/
and howd you let the ai get lv 10 cap ships? 0_o.
the rev is actually thought to be slightly underpowered, actually, as it is rarely seen in multiplayer. I mean, eventually an advent player might get around to creating one, but never in a rush type game.
