Sugestion for dealing with Team Killing

ARGO: 1. Remove the lock on feature on friendly tanks "when your aiming the target will not onlyu grab an enemy tank but also a friendly or even a dead tank" This needs to go.
2. If your going to fire on a friendly one of the crew says "Are you sure you wanna shoot an allie?" and stops you so you have to press the fire button twice to override the crew warning.
I think not only will this stop an accidental TK but will also insure if you do get TKed than the person DID do it on purpose.
