Cast emotes should be usable in battle, toggleable in the options similarly to your victory dance, to override your wand cast animation. As just a standard emote there aren't very many use cases for them, and given how high tier of a reward this is in the scroll of fortune people deserve to be able to use it in battle where it would make most sense. It also wouldn't be viable for battle if it just replaced your wandless animation since that's a massive sacrifice of stats. Seeing as you already have different animations for each wand this shouldn't require a massive overhaul of anything so I'm not entirely sure why this isn't implemented already.
