Biggest needed change to ranked balance: queuing as a role.
Am I the only one tired of losing games because I happen to be further down the pick order, and watch in horror as some REALLY bad player takes my best role(middle), proceeds to suck on fire, and cost us the game?
This especially enrages me when it's MY damned promotions being ruined by them. How is queue order at least not partially dictated by people being in promotions?
Added side bonus: Gets rid of a lot of toxicity stemming from people wanting the same role.
