I just hope that this scoring system won't be as bad as mania's. Indeed, I honestly feel like it's the worst for tourneys, why?
Because you cant make advantages of players' consistency in terms of comboeing (not sure about the correct word to use there). Before, in team based tourneys there have been a lots of tight match that has been disputed throughout maps because people had combos while other had not. I honestly feel like consistency is what people want to see, they want amazing combos more than "amazing accuracy" which is not relevant on long songs.. holding combos is harder in tournament than holding accuracy IN MY OPINION.
Well, i think i am pretty confused in what i say, but if it appears to be close to mania's score system, then i highly disagree with your choices.
