I really don't understand why does that have to be disallowed, if you see him "sliding around", it's a litefoot thing what exists on SA-MP, you gotta figure out how to do it, or just YouTube it.
As for, the "having suspucios shots + suspicious dmg system", come on, this is completely bullshit; since you know we're on server-sided, and every damage registers, so there's no way of absorbing it, and his "suspicious shots" are more of a headshots.
Fire issue is all because of desync - you see him burning on your screen, but he's not on his own screen.
Dismissed.
