I'm lost at this point I think.

Quick sum up before i stopped playing for several seasons I could hold onto diamond rank even in solo q, came back and noticed that plat was harder to manage getting through, this season I have managed to make d1 in rumble, and snowday, but my 3s and 1s fell off to g3.

I know I'm not bad, I'm not great either, but I've played enough the last few seasons to see players that where clearly carried up by high ranks, and get crushed in a match, while others seem like they should be higher up the ladder.

Why are the ranks so messed up?
