The REAL problem in wotlk BGs
Premade AV is the reason why BGs on warmane are no fun anymore.
A Premade group in BiS gear can easy destroy a BiS group of random casual players.
probable solution:
1: dont show wich BG you are invited in so Premade AV wont work anymore (Premade AV got disabled on blizzard servers for same reason)
2: implement rated BGs so they can still play sweaty but against other tryhards.
honest truth:
i will leave warmane asap as soon as wotlk classic realeases. And i think many other pvp players think the same way.
