I've had a little talk about this at the server with Jesus earlier tonight. It can be really annoying that someone uses more smokescreens than they shoot actual bullets. A smokescreen every now and then is ok. It could be useful for the objective etc. You shouldn't overdo it though. It could cause lagg for some players and it's... well, just stupid Can't see a bloody thing.
I was wondering. Is it possible to put a limit on smokescreens, like there is for grenades? Let covert ops start with like 2 smokescreens instead of limitless.
