No ragdolls arent the whole game, but in my opinion its one of the funniest parts from the game. Its really epic if you get fixed on the wall coz of an archer, or if you fly away coz of a fireball. I really like it.
No one said that it would be absolutely impossible to do the same with body parts - or even make a body-part looking like the whole (or most) of the body.
Btw I bet if you would remove all plugins the server would lag less x3
We already tried that and there was no difference.
