I think Heavy should have a hammer and sickle like this. The hammer (Mouse 1) would deal very high knockback, while the sickle (Mouse 2) would deal negative knockback, hooking players in towards you. The main gimmick of this weapon would be that it also works on teammates, minus any damage dealt, for the purpose of repositioning them.
