New diff. Concerns, Oni, And Legacy Random select

[prefx]

As the title states I've got some concerns regarding the new difficulty set-up.

My current concern that's top of my list is the random selection of songs by difficulty on legacy... As I know the 13th difficulty was added to the random song chooser before I'm sure 1-20 can be added with extreme ease, But while we're on 1-99 Could we please have 1-99 to select through? I can't play with my normal style as it is now and I'm discouraged to play because I have to actually select each song instead of going in and just randomly keysmashing whatever randoms up next.

My second concern lis regarding the guidelines for Oni when we go to 1-20 or 1-99 or whatevers happening there. Will the guidelines be changed, can the list PLEASE BE UPDATED WITH NEW RELEASED SONGS, and in gneral can Oni be re-defined with the changing of the average skill level of players and again... UPDATE DAT ONI UNLOCK LIST.
