Low Priority Queue

So my computer was acting weird earlier and I ended up having to afk for like 5 minutes in a non ranked game. Now I have to wait 20 minutes just to play a round. This is a bs rule. I think the low priority queue should only be for people that afk in a ranked match, i mean seriously, non ranked matches dont count towards hardly anything, its bs that i have to wait 20 MINUTES just to play.
