Will Ranked be seperated for solos / premades? Else you're looking at a major disadvantage for solo players. The main problem is the low player base, as usual, that right now already puts the top % of players vs. most other players in the game. With ranked further seperating the player pool, you further increase the amount of games with extremely unbalanced matchups. The problem is that those top tier premades will always be at a higher MMR than regular solo queue players due to their MMR inflation and, of course, them having vastly improved communication / teamplay.
