Matchmaking changes?

So i havent playd about a week. This past weekend i've decided to try new operators and that was... frustrating. Apparently there is no more low lvls in this game cause im always matched against lvls 150+ or 200. One time there was a team with lvl 300. Like wtf? It's casual btw. I'm getting tired of bullet to the face from out of nowhere simulator 2017.
