Rocket League Competitive Ranks
Rocket League started a new season recently, and Psyonix included an update to the ranking system that, put simply, attempted to redress the ranking drift that had happened over the last few years leading to inflated and deflated ranks in 2v2 and 1v1 respectively. It's well explained by NorthstarUK here.
It's been a controversial move, but I put together some plots from the published data from Psyonix around rank distributions in different modes (reddit post here), and they pretty clearly show how imbalanced the ranks have got over, with D1+ ballooning in 2v2 recently, and collapsing in 1v1.
It feels terrible to suddenly be 2 ranks lower than you were last season when you feel like you're playing well, and Pysonix clearly needed to communicate this better (it was only mentioned after the fact in patch notes), but I hope this shows how necessary something like this was.
And I say this as a hardstuck Champ.
