A thing about lower priority.

I have recently been forced to wait another 20min because i accidentally accepted another request. Shouldn't after you wait for lower priority to finish you can play a game without waiting? Like when you leave the champion select. You wait, you join another, you play without waiting. Think of the harm it would cause for people to stress out when they have to waste 20 more minutes on waiting. Meaning 20 more minutes of radiation.
