Rank Decay when I'm active

Yes, I know there must be many threads about this issue. But it surprises me that I drop 5 points a day for both SR and TR even I just play both of them in two days. Not sure how this happens and when it will be solved. But it’s definitely disappointing that I need to play a few more games to keep my rank.
