STOP asking for 2-2-2!

This is true and I agree with you here. Unless Group Priority Matchmaking is removed where a 6-stack can play against 6 solo queues, there is no incentive. However this leaves the perception of that single match to look really unfair for those who are solo queuing which seems to be a priority of the development philosophy of this game.

This is actually a myth that has been debunked by Scott Mercer.

Really Role Queue/Forced 2-2-2 will answer some of the issues that I have addressed, but not all of them of course.
