I think you'll have to just rework your entire matchmaking system
Here are the waiting queue times this morning I've faced :
- ARAM : 8:34 (I abandoned after)
- Flex : 10:12 (I abandoned after)
- Draft Pick : 3:54 (I abandoned after)
- Flex 3v3 : 5:04 (I abandoned after)
- Coops vs Ai's : 1:12
I mean, I couldn't queue in any of your leagues... and i'm just gold III elo..
