Its impossible for Dynamic Queue to work
Pre-mares and Solos cannot be put on the same ladder, this fundamentally doesn't work even if the matchs are "even". Because your taking two different types of players , which basically don't even play the same game, and putting them against each other .
Also adding the fact that you rank groups individually when that's not what there rank actually reflects .
It also undermines the value of being a solo player, what good does my rank mean if someone else got there by an easier means (pre mades) that's bullshit and makes my rank feel worthless. There is no way you can change that fact by irative tweaks. Since its a fundamental problem of what the system is.
These are the fundamental problems of Dynamic Queue, which I repeat cannot be fixed by any means unless you remove the system since the basis of it (pre mades and solos on same ladder) are what causes them.
It doesn't work and will never work. I know you have a lot of hope for the system Riot, but it just doesn't work no matter how hard you try. Please bring back a real Solo Queue (Or duo at least) by the end of Season 6. You tried you experiment and it just didn't work. (Also stop going radio silent after in the video you said you wouldn't keep going radio silent )
