I'd hope it's at least changed to something more useful like learns/uses dance moves faster. Also while on the topic of oricorio, is there a professor focusing on them? Since it's a pokemon with 4 "variant" forms but no "original" and can even swap between them?

Sure, but in the games it's an extra action in addition to whatever move is chosen, while your description just seems like an objectively worse copycat, which i guess is more realistic, but it completely ruins oricorios only use.

And what about dancer? Is it just completely changed?
