What's with the match ups?

I reached lvl 39 and became emerald, I only get paired up with high level people, lvl 80-250 with like 10,000-20,000 points on a champ, not only that but some consider themselves so good like they're some kind of faker, the toxicity increases too it's not like when I was in gold, people complain who I decide to play too harshly, what's the fun in ranked if you're being judged for everything you do or they'd blame someone else for their mistakes
