Cruiser turret balance: http://img824.imageshack.us/img824/9449/cr...rretbalance.png
There are no big range or speed differences for those turrets, neither any other reasons, so why are there such big energy efficiency differences? (sorted by dmg/s btw)
Colonial cruiser agility and speed:
I know I read somewhere that it has such low agility "to make up for it's amount of turrets and the good arcs". So, 1st the agility is even lower than on ALL heavy cruisers - it's even lower than on the Necrosis battlecruiser - 2nd, the size of the thing is almost equal to the RM cruiser, 3rd, the arcs aren't that good:
2 Class 7 360° and down, 2 Class 7 forwards 180° and up, 5 class 6 forwards, 8 backwards, 7 to the sides, 7 up, but only 3 down! And that's a big weak point there.
My suggestion:
Make it a heavy cruiser, give it a bit better agility so it is equal to the other heavy cruisers, more armor, more bb. Easiest solution, even though I'd prefer to see it as a decent medium (sized and "agility'd") cruiser.
