In our 3on3 yesterday it was pretty balanced yeah. First thing i thought about was defending bombsite b with two AWPs in 5on5. 1 CT Tunnel, 1 Platform.
I would go with cbble, i really like the classic feeling and always liked the challange to retake that B bombsite.
I also must say that i'm really into your work and would be glad to test new ideas or come up with some if u wish (regarding the WIP Thread ).
