Hey Riot your Match Making is Blind
each team has two that are Under 40% win rate.
So It puts them as Jungle and Support on my team And Top and ADC on their team but gives the BEST champs on the enemy team as Jungle and Support
Guess what team wins?
My support feeds and lets my ADC die while the enemy jungler is all over the map getting objectives and ganks and the enemy support is making up for the trash ADC he has who is getting kills from MY support and then the 1v2 ADC
Match Making is BLIND to WHO goes where and HOW important that role is.
