My normal MMR is too high
I normally give it my best in normal games and have more than +100 wins over losses. You can call me try hard or whatever but I dislike losing for no reason when you can win. This has lead to an annoying problem. Almost all of my normal opponents are diamonds or high plats now. While this is good for working on champs I know it makes it nearly impossible to learn new champs or roles. I'm trying to learn top right now and am just getting destroyed completely. I wouldn't mind so much if I had experience with these champs but I'm trying to play them for the first time.
Is there anyway to lower my MMR without just losing a ton of games?
