Demotion Series (idea)

So being an avid solo qu.... I mean dynamic queue player, one of the most stressful parts of playing ranked is being demoted, which at this moment i feel can be a bit random. I've noticed when I hit 0 LP I sometimes lose 2 or 3 games before being demoted. So an idea I had to solve this was, Demotion Series. Basically its the opposite of a promotion series except well, if you lose two games you get demoted. Another thing I was thinking is that instead of gaining a free win when you finish your series, you instead get a loss next time you enter demotion for that rank until you rank up or down.
