Why do we have to go to heart of the mists?
because anet wants you to be able to play other games while you wait for your 8 minute queue to pop. its very thoughtful of them.
I believe it was intended to lower the amount of 4v5s or something. or ppl kept canceling. some dumb reason like that. And guess what! we have tons of those still. problem is not fixed and we still have to wait around for no reason.
