Probably the archetype of 'transformations' (in Fern's case, as a speculation) being pseudo-locked to specific class combos, such as Ghost/Hexer, since other methods of transformation are vastly overshadowed and/or other transformations beyond Death Knighting are plain boring or under-performing. And the fact that you're always transforming into a Spectre Knight, no matter what theme you're trying to go for. Or always having to be a Hexer even when you don't really want your transformation to be tied to dark arts.

There's no freedom of creativity for our anime power ups beyond an Eventmin's interference.
