Matchmaking

Matchmaking is killing me in this game. I accept that I'm not that great. I'm not. I play for fun. I'm currently ranked Bronze 1, but haven't played ranked in over a year. I did my placement matches, and basically never did it again. I went to play a matchmade normal, to play some Yasuo mid. Lo and behold, the enemy has a Diamond 1 Evelynn Jungle. She destroyed my entire team. One person was unranked, one was Gold V, one was Silver 4, another was Silver 3. So we had one person above Silver, and they had a Diamond 1. I have nowhere near the mechanical skill required to play against someone who's that good. And this is a constant problem. I'm generally against people plat or above, and I feel completely outmatched. It's frustrating, and feels unfair.
