the crit rate for everything is the same except for melee crits
the only way you could change the crit rate is by a crits chance plugin (i know ive used it) and looking at the cvars of the ocr server i dont see that plugin installed so it should be the normal rate
ive seen people crit hacking, but with that every shot they fire is a crit, and its really easy to pick out and ban for so i doubt thats whats happening, but maybe at some point tonight ill hop on the server and see if i notice anything suspicious
one of MANY reasons you should never use the backburner
crit fire is a big deal (although obviously not if crits are off)
