Blizzard has commented on a Community Council Forum Thread, in response to the discussion around PvP for Wrath Classic.
Hello. I’ve been keeping an eye on Classic PvP, and I can answer your questions.
Season 4 is our last Season with Arena teams, and it’s important for us that players are rewarded for their skill and their effort accordingly. Now that we’re approaching the end of Season 4, we’ll keep in mind the feedback from all of the Seasons during Burning Crusade Classic.
