Let's be real. If they gave us the statistics saying that the majority have no issue with and are continuing to play Dynamic Queue, would anyone who dislikes Dynamic Queue believe them?
The sad fact of the matter is a resounding No, because "Riot can make up and forge whatever numbers they want hurr durr".
Rioters could work until their fingers are numb putting out factual information proving that Dynamic Queue is overall better for the game, but that won't shut up the detractors. Nevermind all the insults, rage, and threats they'd get in the meantime.
So that time is better spent on taking steps to improve Dynamic Queue and deal with what issues there are, making it a more pleasant experience for those who take issue with it.
