The current default hitboxes use an extra and useless (in my opinion) entity. I think it might help large servers getting less resources load if every single player didn't have an extra hitbox entity which is used only for prone anyway.
Some screenies I took on hitbox debug mode:
(the green square, that's the entity I think is useless)
As you can see, in ETPro an extra box entity is added only to the prone animation, though I don't know which solution is better (current silEnT's one or ETPro's) when talking about performance, I just wanted to bring this interesting subject to the forums, I hope you guys (developers) know better than me which one is better .
