Is Roll Queue a valuable system or a mistake?

it has less trolls players with the roll queue system now

The role queue is, to my mind, a big update for everyone.
I have been been playing this game for 3 years

Its was the Biggest Mistake ever. I haven't played the game since!

I think role queue is okay in competitive but putting it in quick play was a mistake.

sorry if this is considered a bump, they are now considering changing it from 2-2-2, to 3dps-1tank-2hearlers , i hate that
