[Suggestion] Changing Ranked

I'm still newer to the game, I'm coming from Dota2 (I enjoy both games equally and they are both fun). And when I look at the Ranked system I feel as if there is room for improvement. What I'm talking about is giving Solo Queue an individual league and then giving Duo/Trio Queue a League, (5's unchanged)

I ask this because I like playing with friends (in Duo) and I also like playing solo. But I don't want to have those to seep into one another (so I can gauge my skill levels).

I may be overlooking something, but it seems like a good idea.
