I want to report another bug.

Before 3.0, when you were in queue for arena, was possible to click on 'esc' *on on keyboard, go back to the world map and do all your other stuff while waiting to get matched. Now, for arena, is no more possible, if only in matsuri wasn't still possible to do it i would have thought about a modification of the general mechanics of the queues, but since for matsuri queues is still possible to click esc and do your other tasks then i think the fact for arena queues you can't do it anymore is a bug.
