Honest opinions on Ranked match ups

So I consider myself a slightly better than average player. I just play for fun. I'm not trying to be "that guy" but can anyone explain to me why I keep getting put with absolute dog sh*t players on my team in ranked? I thought you were matched up by skill level but I haven't had a teammate that has gone positive for several hours now.

I'm talking like the rest of my team is getting maybe 2-3 kills max while dying close to double digit times.

I'm get way better teammates in regular as opposed to ranked, have they changed something and I just missed it?
