In the old ELO-based ranking system it was also possible to get “stuck in gold rank” if you weren’t able to continue to defeat a harder class of opponents on a consistent basis.
In the old system people complained “I won a bunch of games and got small medals each time and then I lost 1x game and lost a bunch of medals! I’m stuck in this rank!” We struggled to explain how ELO works.
At least in this system it’s consistent and easy to understand — if you can muster a 51% winrate eventually you’ll rank up.
There’s an existing active thread on the topic of “I don’t like flat medal changes and I think it can get stuck”. Please continue the conversation there: Multiplayer doesn’t make sense any more
