Si I agree, but there is also playstyle number 3 that I commented on a different thread:

McSic If you reading this then at the very least make it so that if you throw sticky nades at the enemy it explodes immediately. I've seen people having friends on the opposite team so that they could throw sticky nades at them so that they then could run to one of their allies and tell their friend on the opposite team to make them explode, there is no way to defend yourself against it if your ally are carrying it for enemy.
