So I have made a team for us on the bf3 ladder for gb.com. So during some point in the bf3. I will most likely hold tryouts for TOP spaces in the gb team. So you won't necessarily not make the gb team, you just won't play often. Mow I will have TOP spots for both core and hcore. however, in the past, championship matches have only been core unless agreed upon between both teams that we'd play hcore. so i recommend trying to get experience in both core and hcore.
Anyways, I will be running the gb team in case you haven't guessed that already.
