Seriously contemplating uninstalling

The matchmaking system is buns. I’ve made posts about this before and it seriously is horrible. I mean it’s gotten to the point where it isn’t even remotely balanced anymore. I was just wondering exactly how hidden mmr works? Because there’s no reason why me, who’s grinding through bronze right now, should be against a plat 1 player on the cusp of ranking up to emerald when our highest player peaked silver. I’m just wondering exactly how they thought this was a good idea?
