I'm sure someone will correct me if I'm wrong, but once open a time there was one from what I can recollection, but it was shut down due to low player activity. Personally I font think a whole server should just be awps only; But I could see if you alternativly suggested a 1v1 Server. That might have a better chance of being a thing.
Regardless if I want to see it or not though, I'm sure if you can muster the support for it and maintain a recurring player count consistantly decwnt enough, I dont think theyd say no.
Disclaimer; I could be wrong in multiple areas here. We could've never had such a server, and its not guaranteed that CSLE will move to support it, or they could always spontaneously say screw it and do it anyways.
