How is this going to help new players? I don't get it.
play atleast 30mins - by playing 30mins
Or they'll just RQ because they are being sniped from every angle with sniper and unable shoot back 
I tend to avoid the "register for x feature" servers, because usually you register after y minutes and you find out that you have to play more for the next feature. I think this may turn people off from the beginning, not to mention that it's unfair to some players who don't register for whatever reason (no names please, I don't want someone trolling them). I don't really like this idea very much, but if for some reason we do decide to go this route, 30 minutes is a long time to wait. 30 minutes of realizing that people gang up on newbies without having the ridiculously OP weapon they're using on you is even longer.
Also, I am strongly against discouraging anyone from going undercover. For some people it's the only way to play the game without constanly thinking about how to avoid offending their friendies playing in the opposing teams. I would rather see everyone going undercover and the game being played properly.
P.S. I actually encourage everyone to play undercover. Go ahead, fight everyone and have a real fun. 
This is a symptom of a cultural problem, not a fix for anything. It's up to the regulars and clans to actually play the game and set an example. Most people here are really good at this game. Always playing with, but never against friends and clan members deprives you of the opportunity to experience them at their best and learn from it.
I'm not against people going undercover, but I think it's not something that should be accepted as normal.
Remove fast skins, that shit is more unfair than anything
In my opinion, we don't need sniper and saw in every map like LS, SF, LV because these maps are fast and don't need much effort to finish the map and for protecting team as well so I think we should give rifle in replace of snipe and remove saw for fast maps.
The real suggestions^
