Just had an auto-filled duo queue in a ranked game. Is anything even being done to fix this?

This should never happen in a ranked game, period.

Even worse, one of them was auto-filled to my secondary role. I could have swapped with them, but they just said something like 'lmao wtf inc feeding duo queue,' and didn't explicitly say they were auto-filled until the game started. Looking at their match history, it's pretty clear that they were queued for top/jungle and mid/top.

This system is garbage. It doesn't work well, and it's obvious that it aggressively auto-fills to try to get games started within 1-2 minutes. Maybe this is fine for normals, but it's completely unacceptable for the competitive game mode. I think I actually wait longer in normal queues than I do in Diamond ranked queues.

What, if anything, is even being done to improve it, and why has it been left unchecked for so long? I doubt that anyone who plays ranked at a remotely high level thinks this system has any positive impact.
