IDK, it's still seriously tanking and almost as if RITO just wants people to be far below what they were as some incentive for people to play a massive amount of games to grind. The time it takes for each game and tiny amounts of LP you get for it is why I just get to gold each time for the skin reward then stop and play on my other accounts.
Even less incentive now to rank up with so many different ladders in solo, flex and 3s now.
IMO SC2 had an amazing ladder system where you can get promoted just from high performance and not have to grind out 100LP and promo every time, and the season resets would put you near where you were before. If you did really bad you'd tank out a lot faster than here (needing a whole tier MMR drop to drop down is fucking stupid) but could rise faster so you get much more even games rather than slugging it out for a month with silvers to get into gold as a plat player.
