I LIKE Dynamic Queue
First of all, I am A SOLO PLAYER. Yeah. I have no issues with dynamic queue what so ever, at all. I have been matched up against premades, sure. I've lost to premades, I've won against premades. Heck, I've even been 5 solo players against 5 premades. The thing about premades is that the gameplay style changes. The premades are forced to play as a team more, and communicate more, as we're likely to be higher skilled players as the MMR changes in a good manner. I've personally climbed from Bronze IV to Platinum I so far this season, which has been alot of fun and tough times. I've checked every match, watched if they're premades, and I've roughly won about 50%~ of the games against premades. Now, sure, I might be low elo, but the fact that premades apparently totally ruins games and makes the game anti-fun with no competition is very false in my experience at least. It just means adapting your playstyle to that. Dynamic queue and the new champion select is great, and as a patient person I have NOTHING against waiting up to fifteen minutes to get in a champion select AS LONG as I get my preferred roles. As you always will get one of your two primary roles obviously the queue will be longer, which is fair and has no fix. In my experience, I've been matched with and against roughly the same elo as myself.
TL;DR I, as a solo player like dynamic queue and I am ready for it to stay. Riot's new champion select is cool, and I don't care about waiting fifteen minutes to get in a game that actually suits my playstyle rather than being forced into a role I do not enjoy.
