If they added it, they'd probably feel obliged to go in and add parser checks and such to some interactions (like Hethia at Logging Camp) or negotiations, or mentioning the Champ as arbitrator, and during the Wyld tree/dungeon quest. I don't think they want to have to go looking for spots to make it worthwhile or mentioned in the story (rather than just having a cool new class).Maybe a druid class or a class with nature spells would be nice?
If it could be pulled off, it might have to be an added class that doesn't become available until later (maybe the druids and city elves have a breakthru and one offers to train you), then they won't have to worry about including it in class check parsers from earlier (maybe in a Hethia convo or sex scene, but that's far easier), and could allow for future scenes to take it into accounts.
But still not likely, more likely to just get more plant or animal oriented spells and let you roleplay your Champ with them as a druid.
