i had a similar idea. but instead of freezing it would shock 1 tank and if there is another tank close, the elctricity would shoot to that tank. Kind of like area damage.

I think there should be a turret called the Falcon. It basically shoot a bullet high in the air and lets you see i the perspective of the bullet. You push space again to make it plummet down. The advantage of this is you can kind of spectate. The disadvantage is that you cant see your tank when in bullet perspective so a close range turret could take you out. There is also a hull I was thinking of called the ram. It has a special "Ramming Ability." If you hold both right and left arrows at the same time it will speed up quick and ram, which will do damage. The protection of this has to be bad, to counter the attacking ability.
