in which other than the 1 million max score, the currently listed changes are:
>has starting HP like all other game modes
>sliders (which are drumrolls) and spinners have the same behaviors like those in all other game modes -- except CTB in regards of spinners
>drumrolls and big notes, elements whose purposes are to reward bonus points for more skilled players, become mandatory in reaching the max score
...because it just isn't bearable to let this mode be of enough uniqueness ('uniquity'?) compared to the other modes and it has to be some sort of 'standardized' to the osu! environment, to the other game modes. Taiko that ISN'T Taiko? Might as well ditch the "Taiko" in "osu!Taiko" and rename it to something else.
this new system would definitely fuck up Taiko's current foundations (including but not limited to the Loved maps section) if it ever becomes final, but if you guys want to implement it so very badly, I'd say keep it within official tournaments and ONLY official tournaments, NOT anywhere else. Even if it does get implemented, mappool selection in said tournaments must be WAY MORE stricter and careful in order to comply with the changes that this system brings, although that would 'most probably' (if not 'certainly') need a heck lot of miracles to happen.
if anything, I think some other things need to be addressed before issuing any kind of new system in the gameplay, such as the note-locking problem and the HP gain/loss rate correlation (i.e. the difference in marathon maps VS in regular-length maps).
