true it's pretty sad, bw should just take down all the servers and fix it asap, it's a game breaking bug, if someone exits a warfront or the warfront ends due to lack of people they should get ZERO xp, not full xp!
also anyone who abused it (ie constantly queued up to empty warfronts, obviously farming the exploit) should have all that xp removed.
i won't be rolling on a server that is full of 50's already who got there by exploiting a bug, i'll wait for a fresh server to be released.
