Role Performance is one of the WORST matchmaking mechanics you could ever introduce in >1% brackets where it causes the worst game qualities to be made. Descaling MMR for the sake of faster queue time is horrible for quality games as it does nothing in the slightest to assure a player that they will even get it. Autofill system implemented from it with the Role Queue Game system also makes this extremely hard to get into decent games as well as you're gonna have scenarios if not every game where someone is going to be filled on a role they have low skill on and throw off the lack of hero pool they are gonna have on the role as well as lane knowledge which is insanely important in 5.6k+ games. Its a system that never works in making quality games. Getting games is already tedious as hell if you arent queue US east which is already a massive joke of a region to play once you hit 5k+ and it forces people to have to either play US West which is already high queue time or region hop to EU where its still high queue time past 7pm est. Please Valve remove Role Performance from 5.6k games. It does more harm than good and needs to go! You make people have more reason to play that bracket where quality is actually viable and you even solve the problem of people making alt/smurf accounts.
