They should have a round robbin queue, so it tells you what you will be playing next. [Tank] [DPS] [Support] in that order, over and over again.
If everybody was put into this queue, there would be no wait times.
Yea you would have to play tank or support when you only wanted to play DPS, but tough. Or join the 30 min DPS only queue.
I haven’t played DPS in like forever since they introduced this crappy RQ system. I miss playing Ashe.
