Wat do if rank doesn't drop?

I remember people hyping the ranking algo back in the day and discussing how epic it is that your rank will not be reduced if your teammates continue to suck in the future matches they play, because obviously each individual playing this game is always the mis-ranked "I need to carry my team, I would be rank XYZ if my teammates didn't suck" player. Anyhow, I beg to differ and I'm actually quite ok to admit that my team is carrying me most of the time.

The problem being: My win ratio since november is under 30% and I have only played a handful of games where I would have better than 1/10 kdr (not a single one with more kills than deaths!) and my rank has only been increasing regardless. Now every match is a total rolfstomp joke where 11 other players look at me like "what the fuck is this retard doing here?" and the person I'm laning against could play with one hand and still walk back with 5 kills and 12k souls while the rest of the players are grinding even at 4k.

How bad do you need to be in this game to be allowed into matches where the "average team rank" isn't 3-4 tiers above my own? I'm not intending to git gud anytime soon either, so enjoy laning against me or get fucked in the team I'm in because you're 5v6 from the beginning!
