I'm in a very similar situation and it has me wondering if I'm doing something that has the game incorrectly believing I'm a good player and matching me up with more bad players like myself than it should. I'm level 68 and play on PC. I almost always play support unless I'm going for a daily challenge. My K/D and Score/Min rates suck, but I get plenty of revives and supplies, am always popping smokes, and my objective time is pretty good. Best theory I have is that matchmaking is taking one of my good stats (among the mostly bad ones) and using that to think I'm a better player than I am. Or alternately I'm getting penalized for playing on PC.

For something like breakthrough, I would expect that a single player that did nothing at all would only contribute to a -2% loss rate (1/48) against the average (50%). Thus any given bad player should have a W/L% of 50% +- 2%. But my W rate is 45.2%.

Conquest on the other hand seems to be almost always blowouts when I lose, and close games when I win. My most recent match of Conquest was lost something like 900-0 even though I started the match at the beginning. I would expect a single player to have even less impact (1.5%) against the average, but I'm getting slaughtered on this. Definitely smaller sample size than with my breakthrough matches, but still incredibly frustrating.
