1. It's a training map for starters, ever since I first played CS:S I first joined the snipers server (I was using non-steam back then, 2012)

2. I agree with this, but most people prefer playing for fun and CS:S is about to die (CS 1.6 got more players according to Steam Statistics)

3. Removing a weapon should not be a reason, that's why those guns lasted in the game for so long (It means that most people are fine with it)

4. I disagree, AWP and Automatic Sniper Rifiles should be only allowed for purchase when a minimum of 14 players are online, this is to avoid the round to take so long when there's few players.
