not sure why this is suddenly a huge issue, it's been very well established, and even if someone happens to misjudge the difficulty of a map, they wasted one play, oh no, not really a big deal at all. as long as there is still logical and clear spread within the set, having the top difficulties be more creative or individual in their naming shouldn't be a problemiirc this rule has been set for over a year due such things like that.
and then what about Taiko diff names since words Kanta, Futsuu, Muzukashii & Oni are not english it is also confused many new players.okay wait, we're talking about the issue that Mapper are using their User names as Difficulty name, that's the main issue. To Sakura's post I find custom names good as long they are related to anything in the game, serie, whatever. I made that pretty stupid example with woof (given from GoldenWolf) and that's more as obvious why you should not use unrelated Difficulty name(s). A question about logic, not about rules if you ask me. Kantan, Futsuu, Muzukashii, Oni are the basic names of the original game and be kept. If you're nagging about the lack of understanding a different language except english then such Names wouldn't be allowed.
and About mania since there's different key count , do we need change them to something like 7K Hard, 5K Insane, 8K Insane..etc
The Thread name is a bit misleading, would be great if it could be fixed.
