How about an in-client survey about Dynamic Queue?
I can acknowledge that the system is flat out broken right now, but even in its Riot proposed ideal form it does nothing to accomodate for me as a solo player. According to Riot 5 man premades might be matched against not 5 man premades in ~5% of games (source, scroll down to "Dynamic Groups").
That means I, as a solo player will have to put up with being matched against Ranked teams in some games, where that wasn't the case before, probably paired with a 4 man premade. And this is just the start. Now there'll also be 3 and 4 man premades I'll also have to put up with in games where there isn't a 5 man team.
This results in my impact on the game lessened, since premades have higher impact. It becomes about which team has the better premade and less about how I do in the game. So even though the system is just flat out broken right now, it does no good for me as a solo player even in a perfect iteration of the system.
Another thing Dynamic Queue does, is making ranking flat out meaningless. Let me give you an example:
Person A only ever queues up alone. - Person B only queues up with four friends as a 5 man premade.
Let's say both reach Gold V. In Riot's ideal proposed system they probably will never ever play against each other. They won't even play against the same playerbase, since Person A mostly plays solo players and tiny premades and Person B plays against 95% 5 man premades.
How are their ranks comparable at all? Their games require a vastly different approach and set of skills, with A's games being much more focused about his play and B's games more focused around map movement and communication.
They get the same rank though - "Gold V" - equally skilled. How can Riot claim they can compare these two players on the same ladder, even though they play a totally different game?
Since Riot is so adamant about keeping this, even though it might alienate a lot of solo players, how about a survey to check how the ranked population actually likes this change? I'll gladly shut up about it and move on if the playerbase votes to keep it.
