going back to swarms, I still prefer a fix of gouping ships according to FAP purchase. This gives all players the same number of activations in just about all scenarios, unless they buy up.
for instance, in a 5 FAP battle game, if you buy 2 raid-hyperions for 1 point, they're in a squadron of two. If I buy 4 skirmish-chronos, they operate in a squadron. this can also help speed up some games.
if you buy up, like if you buy a 1 war-warlock in the above example, you'd wind up shorting yourself, and have 1 fewer activation. so account for the disparity this creates, the player who bought up can force his oponnent to activate a group (oponnent's choice) before he moves the big ship, but then has to move the big ship on his next activation.
I also think huge hangars need a fix. after seeing a fleet of battle level drakh carriers and a bazillion raiders in a 5 point battle scenario at Kublacon, I think they need some toning down.
