I would be open to a different system…
1st dropped queue in an hour gives you ‘Scaredy Cat’ for 30 seconds, preventing you from queueing during that time, 2nd time in an hour you get 60 seconds.
And the timer doesn’t reset if you accept a queue.
So if you miss a 3rd inside of an hour, even if you just finished a game, ‘Scaredy Cat’ would still be 2 minutes.
With stacks resetting an hour after your last missed queue.
And it should be the same system on all queueable content other than follower dungeons and Delves and all the PvE stuff that can be done entirely solo.
