I'll never understand Jb's rules.
Warning shots with an AWP SHOULD NOW be allowed. Like Phonicz stated, not everyone has enough aim to properly hit the legs. Even so, that just makes the chance of persons getting freekilled even higher. I mean, I'm no AO or anything, but I'd add a rule for it since it falls in the "you can but it's a dick move" zone of the rules. I've been killed by AWPers many times, yet some might consider this as "crossfire". I think everyone has a pistol and should use it for this, not a fucking sniper.
BUT, AWPs are indeed very useful against rebellers, when used properly (meaning that NOT 3/5 CTs have a sniper). I don't want them gone, but warning shots with them seems inacceptable for me, imo ofc.
