Or the first time i tried 5v5 with my 5 shamans at lvl 80 on the night before maintenance, there were only 2-3 other teams playing, so it was a long queue for fast losses. And the dang arena week reset when i was at 9 games.. *grumble*
Havent tried going there since, though i think i'll try again soon since i have a bit better gear and the points would indeed be handy to get gear cheaper.
