I agree the camping idea/rule is something that would be best served by putting it in the rules. IE- time limit-Scope vs no scope. As Autumn said the nade round punishment is not needed, since it has no bearing on the game itself. There should be a rule about running away during a knife fight as well. The T's loose levels when they die if time expires and I have seen people run on porpuse to let that happen.
Slightly off topic but, I would like to see the prior post about the floating bodies addressed.
