Since the recent patch, with "all new and improved ranking system", why the hell have I been out-ranked in literally 90% of my games?

Here's two screenshots of the ones that just happened twice in a row, baring in mind this has been every single match since this patch... I was immortal 1 last season, now cant even break D1 due to being ranked with GOLDS in a diamond game!!!
