C-Bug.

90%  of the players who don't know what is c-bug , also don't know what lead-aim is too. So now you gonna ban everyone who is leadaiming , because it's something that not everyone knows about. Right?

Wrong, we'd ban because of it being bug abuse, duh..

I don't understand your "not very realistic" argument either- its more physically possible for someone to fire a desert eagle as fast as the c-bug using two hands than it is to fire a shotgun with one hand, or survive 50 bullets before dying... in fact, it is one of the more realistic parts of the game.
All the more reason for it to be allowed.

Fair point, you'd probably break your wrist with those sawnoff shotguns, however that's how GTA is set - if R* wants it to be like that, then that's that. However, bug abusing isn't what was intented, and isn't a part of the game. It is instead simply exploiting the game in order to gain an unfair advantage. I'm still with no.
