S rank games worse than A rank

I recently got into S rank, and I was so excited. However, I’ve been playing series, and when I tell you, I haven’t won a game in FOREVER. I’m consistently at the top of my team, and the games aren’t even close. We get wiped. In A rank, my games felt more fair, and I rarely got rolled. My win rate went from about 1:1 to like 1:3 or whatever. It’s to the point where I’m not having fun at all and just want to quit. I feel that I’m getting punished for improving. I don’t even know how deranking works. Is it at the end of the season? Honestly I’d prefer to derank at this point. Anyone else feel the same?
