I dropped 58->50 followed by a climb to 58 again. this matchmaking system is weird.
It can be done. I dropped 10 levels once and managed to climb 15 levels playing solo mostly.
My placement matches put me at 46 (as Mercy - 6 wins, 4 losses), and I've just dropped like a dead fly. The problem is I don't know how to stop playing, and now I've reached the 20s. Wtf happened. When we win, people always ragequit and we get almost NO experience. The whole thing just feels depressingly unrewarding. I also almost always get stuck as Mercy, and I'm kinda tired of it.
The rankings in 40s were much harder to "drop" from than it is now, it just keeps getting worse the further down you go. lol
