Evolved mode has zero failure states

[Absurdity]

Isn't bards failure state that it gets a bonus after doing all 3 songs? so if you repeat a song before the other 2 have been played you delay that bonus?
or misusing the buffs for each song

From the footage it looks like you quite literally can't play the same song again until you have played all 3, so that failure state simply doesn't exist.
And then there is the issue with delaying those songs for their defensive effects. They cost a resource that is auto generated and all your non-filler damage is tied to using them, severely limiting how long you can delay them.

It's kinda like tying Shake It Off to Inner Release on Warrior, it doesn't make much sense.
