Do you think dynamic q would be better if you couldnt start out with a 5 man premade? Maybe just a 3 man, and then you can easily absorb solo's that you worked well with in games. So its dynamic in that your squad should be growing while you play.
There would be more knowledge and skill involved because recognition of players that were actually good takes some game knowledge. So people who are better at recognizing skilled players would climb better than someone who only looks at kda or dmg dealt.
Edit: I think 3 man groups need to stay at the very least, because thats the only way duo jungle meta will ever develop. But thats my pet meta, which I would like to see come into power.
