A Few ideas...

How to fix over 80% of the hacking problems? No br's
Another idea, we have all got that gun that we bought or won but don't like anymore, why not make a trading thing like a tab for the game, like next to item shop. We could make rooms stating what we have and what we want, and someone joins and we trade! I'm no coder but i think it's possible to put in, and would make things better. Z8 would't really lose money because the gun is still payed for, just handed off to a new player.
We need more MALE characters also, i'm not saying i ain't gonna be one of the first ones to grab FOX up if she comes on the market, but some people just don't like female characters, making GSG9 overused(If thats the right word for it)

Also, another edit, US/CANADA SERVER WE SHOULD HAVE A SERVER WHERE IT ISN'T FLOODED WITH NON ENGLISH SPEAKING PEOPLE AND BR HACKERS! NA CF SHOULD ONLY BE NA, SA SHOULDN'T EVEN BE THERE
