Dynamic Queue vs Solo queue- Casually Competitive

So I'm sure the majority of us have seen posts with the pros and cons of dynamic queue when it comes to competitive player.

I've played across many different Elos on many different accounts in dynamic queue(Peaking at Platinum II series so far). I have to say that for Bronze, Silver and even low Gold- Dynamic queue is great. It gives a great new inviting experience for newer players and allows them to play with friends without all the anxiety that ranked had before. I had many many friends that would never play ranked because it was so daunting- that now play it as if they always had.

But as you climb higher up the ladder there are fewer players and larger skill gaps. Queue times become increasingly longer and games become more and more tricky to balance- especially when variables like teamwork get thrown in. I know a good number of High Elo players (Diamond 1+) That Just stop ranking on accounts when they hit around the Diamond 3 Elo. After that most of them just make or buy a new account in order to continue to play with low queue times and with friends.

But instead of Arguing over which type of player riot cares more about and which system benefits what type of player, why don't we just separate them? Until you hit Platinum you don't experience things like Ranked decay- and the majority of the players that get to Platinum are pretty competitive players. In the same way that we separate whether or not we have ranked decay- why not separate our queuing system?

Low elo players would get to keep the perks of playing with their friends- and High elo players would get to play in a competitive ladder again.

Platinum level players could still play against Gold level and high platinum level players- But they would be required to queue up as either a solo or possibly solo/duo queue.
