There's something wrong with the Nova tri-class skin.

To my knowledge, It's the first "vanilla" tri-class skin (no new animations for hero power,no entrance etc), however, for some reason, when you play as paladin, you DO get a custom hero power animation, even tho it doesn't really fit Nova, It looks like Yrel's or Liadrin's hero power, I can't quite recognize it directly, maybe It's new altogether, someone with bigger knowledge in these skins can maybe tell.

I don't see anyone mention it, neither written in game. Can there be some kinda clarification whats up with this skin? Was she supposed to be a "full price" skin like artanis or raynor before the idea got scrapped and left us with weirdly only Paladin animated?
