PSA: If you're getting long queue times (1.5x the estimated wait time), leave and re-join queue.
The queue is bugged and sometimes breaks and stops searching for a while. This can happen even after a match has been found and dodged in the same queue.
You'll see that a match will be found very shortly.
It's not new champion select's fault, it's not the lack of supports' fault, it's a bug. If you wanna complain about it, do it in 'Report A Bug', not here.
