I don't mind longer queue times...
I can accept a long queue time, sure 15min is a long wait, sometimes even longer queue times depending on the number of dodges, but i lose all my will to play when i see: 2 siver borders 1 gold border 1 platinum border (usually me) and 1 diamond border
Sometimes a master tier or a lvl +20 player, or sometimes both in different teams! I don't mind long queue or being autofilled into support, but give me some equal teammates and opponents. That's all.
If you wanna see my profile, Feedar com gosto, i play in the BR servers
EDIT: obligatory autofill mention
