Well, just a guess... Don't know if it might be confusing but, wut about if it's player's choice? Like
A wants rc2
B wants RC2
Then those should be together on RC2, The others who wants to be on RC1 battle on RC1... It would give activeness on both releases. BUT we would need 2 servers both for each release, that would be a fucking cunt to put on, and would generate lag.
And I agree with aXXo, like alot.
