2) the first turret mount would probably be better as a gun, but it's up to you
3) it needs either a small boost to it's energy level, not the recharge rate (just the starting level), or to have the infocard altered so that class 9 is the max and class 8 is the optimium.
4) is the amount of armour correct?
if it is then the agility is fine, if not then the it'll need to be lowered.
