I don't think we should restrict any weapons. as sin said, the game is far more balanced than it was in CSS...
the map also changes when a team hits 6 team wins... so it takes you normally 2-3 rounds before you even have the option of getting an awp or say auto sniper.. and if you die.. well you wont be getting one again most likely before the map ends... aside for maybe the last round. everything is far more balanced gun wise, and with it being first team 2 win six wins.. there's just no reason 2 restrict anything.
ive got like 15 hours of ingame time, and Ive barley seen anyone even purchase the awp anymore as it's exspensive, and takes a while 2 get.
I would suggest not restricting anything, and seeing how it plays out before making actual restrictions.
