You can say that the majority don't care about anything ever because that's always true. If you survey anyone a majority will say they don't care. You can twist it anyway you want by placing the majority that don't care on the side you want to win. I can place the side that says they don't care against Solo Queue and it suddenly turns the numbers against Dynamic Queue because that's what Dynamic Queue supporters are saying. What you have to address is the people who do care enough for them to quit playing Solo Queue or Ranked altogether.
20% support Dynamic Queue
15% support Solo Queue
65% don't care.
85% of people support Dynamic Queue. This is insane logic that a lot of people use.
The only thing good about Dynamic Queue so far is that matchmaking is faster, but the cost is at the equal chances of a team to win, which is not okay. You do not place players who are two tiers, not divisions TIERS, in the same game, ever. I should not be seeing Silver 1 and Platinum 5 players in the same game together.
