Removal of dots is just the continued simplification of the game. Eventually we'll get to the point where the game is like Just Dance, Theatrhythm or the twice-used Starlight Celebration minigame in FFXIV. We'll do our button press dance in a certain order and be graded on on how well we timed all of our abilities and be granted a score. If all 8 scores in the party add up to a certain number, you win. Otherwise, you wipe.
