I think we should split the key mode rankings, as they are more different from each other than most might think Typically, the average mania player will stick to only one of the key modes, and will only care about the performance points from said key mode. Seeing this, I think we should split all of the key modes into their own rankings. Quaver has this integrated and it works flawlessly. Another factor is how many more harder maps get ranked for 7 key and 4 key. On a typical day, I can scroll through osu!direct and see many more 7-9 stars for 7k than you'll see for any other key mode. And if you look at the top players for mania this reflects this. Because of this we only have a few 4 key players in the top 100, with them being far away from how many Performance Points the top 7 Key players have. For the reasons I've stated, I think we should move away from the old (current) ranking system of having combined Performance Points for all key modes and split them up into their own categories.
