How is this okay?

Here I am, a lowly Bronze 3. Bronze 2 last season and Silver 4 the season before. How is it that I've been consistently being matched against Plat and Gold opponents? I once had to play a game against a Diamond 5 Yasuo main. Check the match history. That game was miserable. They also had at least one plat on their team too, but we had at most a gold. We weren't even given a chance to surrender, they just won before we could.

What's with the crazy unbalance between team skill riot? Give me some slack, man.
