You should be aiming for weak points and tank modules (ammo rack, fuel tank etc) anyways. So what the heck is the point of this skill?
The only situation that I can see that it's useful is it's on a TD. The TD spots a scout, sees that his radio's damage so he fires and not risking getting his position reported. Or sees that his view ports are damaged.
That's the only situation that I can see this perk being useful.
Anyone else using it for something else?
