cobalt / diciple / skrimishers are a pretty good addition to any fleet late-game
this is cuased mostly by their unique racial ability,
Advent, steal anti matter
TEC, sabotage reactor
Vasari, auto-repair + sabotage engines (not sure about that last one)
this gives pretty neat support + theyre great if you focuss fire with them on either siege frigates, carriers or FLAK
you gotta be carefull about the flanking strategy tough, advent illums will make tht part difficult, instead try to hit the back
(1 flank)
(2 fly through enemy ranks then turn around)
both works. tough sometimes one works better in a different situation then the other
Heavy cruiser class has high health, low to medium firing range and does high damage, only drawback = it being to slow
people tend to rush for Heavy Cruisers, i personally think thats a bad idea cuase if just one thing goes wrong, it's over, al the money spend lost for nothing

(thus the player leaves says im a cheater etc.etc.etc, not a good method...
