This is what you need to make Dynamic Queue remotely competitive Riot!
Ok so Solo Queue is dead, fine... Then this is what you must do Riot.
1: Whatever you do to the top ranks you need to do to all ranks, be it banning 4-5 mans, or making us pick 3 roles instead of 2 it must all be the SAME. They are playing competitive League, we want to play competitive league.
2: Matchmaking must be tuned to be a mirror match 100% of the time! Not 94%, not 99.99% it must be 100%... What I mean by that is if the enemy team is a 3 man + 2 solos then my team must be the same, its not fair or fun to face a 3-4 man as a group of solos even if you make the solos higher rank.
3: You need to address the fact that EVERYONE got placed way lower this season then past season, as well as the fact that your data shows 4-5 mans winning up to 50% more than 1-3 mans for this season so far, meaning your Dynamic system is effectively elo boosting them.
Thats all I got...
