I was playing with the 10k mod when I realized that it's not ranked. I see no reason for this. In fact, I see no reason for 10k, 12k, etc to be unranked as well. It discourages players from playing those modes and ends up players like me complaining (or whining) on why nobody wants to play those keymodes. Also this might have been asked before, but I don't see why the 8k score is reduced (sure the patterns might be easier in some cases, but that doesn't change the fact that it's harder to master), it should be 1.0x multiplier IMO. I can't get the extra PP from the 8k mod because I played in 7k and would never get the achieved unreduced score.
