I'ld just like to see some power draining guns / turrets so there's a new thing implemented in game. Strategy. So what if we don't have a power bots to replenish it, it makes it even more crucial.
I would like to see slow firing turrets (But really, slow) that drain tons of power. It would certainly reduce the lolwut cap vessels awesomness, and ofcourse, you can make flak ones that do simmilary the same to disable bombers or something, because whenever there's 3,4 bombers vs a capship 2 can stand in place perfectly still and aim while big ship is hitting those remaining two.
Point is to balance it somehow. But it would certainly make things more fun.
