Like this, but legend's pack on RTB with the throwing knife should solve your problems for now. Otherwise i support it too.
Off Topic, but somehow related to this :
There has to be a way that when an arrow or anything like them hits a bot/player it stays in the body for how much time the projectile is had to stay, as a lifetime. I'd like this because i hate it when you shoot someone and the arrows just vanish on impact.. i mean it's a bit more realistic, but a little strange?
