How i found out jump + crouch is a very laggy thing. At causes lags for player. If really, during the server there are lags already. If some people try to jump + crouch at the same time, i will cause global lags (if there are 2 - 4 jumping people small lags; 5-6 medium and hard lags.) I found it out when i were playing zs long time ago (last time ) (yahoo! i found the time when i could unlock this trigger). I saw 4 people jumping and i, trying to jump laged also. I didnt even jump a cm. maybe those are just lags and im telling not truth.
