Draft MM vs Ranked MM
Riot,
This has been an ongoing issue of toxicity for an extremely long time and it's absolutely annoying to be quite honest. Why is it that even though I have around 2000 normal wins and about 1600 losses for normals. That I still get put with bronzes in my games in normals. Where theres a mixture of plats/bronzes/diamonds/silvers/golds. It makes me become super toxic when I have an ADC that literally just does not understand the game whatsoever. Why is it that we do not get placed with people that are near our tier of ranked MMR. Because I wouldn't care as much if I was getting matched with low golds mid diamonds what have you. But when you drop 3 tiers there is an absolute skill difference for a reason. You should not be getting matched with people like that when you're sitting mid plat etc.
TL;DR Match normal game MMR to your ranked MMR to produce less toxicity.
