Yoshi-P: "If you want more engaging content, go play Ultimate"

[Nizzi]

It wasn't really that surprising. We've had that sort of motif for a while. Back in Stormblood, we had a cane that literally had butterflies fluttering around the end of it. This isn't something new in Endwalker.

ShB had that too for WHM with the final relic step, Blade's Mercy having butterflies floating (maybe this is what you mean)
It's a bit confusing when SCH got Expedient which has butterflies too... why do WHM and SCH both have this aesthetic choice present in their items/abilities?
