New Ranking System is just BS

Like title, new solo/duo system with different rank for different roles is just straight up bs. When people are playing roles they don't main, they naturally tend to do worse. What's more, because it is not their main role, they practice champion in solo/duo. There were a lot of games of mine in which that there is plat adc player playing top irellia with like 6000 mastery points and got 0/6. Like what the actual **** rito. Can we change the solo/duo system back? Players are just trolling in rank now. What is the point of rank if there are people trolling in every game. Literally every game is ff15 in gold.
