Placements are having a massive negative impact.

Soft reset seems to have a negative impact on your MMR regardless if your MMR raises while you win (7-3/8-2/9-1/10-0). I've watched several of my friend finish placements yesterday for them to have a high overall MMR Gold/Plat for them to be placed almost two divisions below while there MMR is still roughly where they left off before the soft reset.

Someone from Riot please explain.

Because as far as season go, this seems to be the hardest on placements. Cause even if I'm winning games with objectives, and a good KDA I shouldn't be placed with bronze players who don't even know how to capitalize or focus objectives.

There's a huge difference between Gold and Bronze and if your placements cant tell the difference then somewhere on the programming side is wrong.
