Hi, there are a lot of good hero power animations and skins (lot of skins doesnt have animations even the legendary ones) , if we can customize the hero power animations like we can customize de finishers on battlegrounds.
we could customize our hero power depending on the heroes we have, for example that jaina uses khadgar’s hero power animation if we have it unlocked.
They even can sell animations wich i think is atractive and good customization idea
