New Rank system ( Rank Stuck )

[wfun123560.warface]

I have a problem that I can win 8-9 matches in a row and I don’t get promoted higher in rank, then I lose 1-2 games, win 7 games again and it’s all the same, although previously 4 games were enough to get promoted by 1 rank.
I'm an eternal ascendant after the patch.
