I agree noblock should be off but there is too many peopel and people would get spawn jammed so it has to be on.
Sv_pure 2 would be great to have however a lot of people would get irritated and mad because most use skins for playing zombie escape and etc.
Yes because most admins don't realize when someone is walling or using smooth aim /cough k /uncough, server can't handle100 tic with 50 players. Noblock is fine due to when there is a ton of people.
