Agreed. I don't mind the fey being good at social, or us suffering setbacks in the combat. But her superlative skill should be reflected in that combat. Like, if she was, I dunno, weaving some grand vision of human and fey cooperation and almost literally holding her audience spellbound, that would be fine. That would be awesome. But her skill and rolls aren't reflected in the update, so it feels that she is just doing something normal westerosi ladies might, except it works.
Or, you know, given that the fey raised horas redwyne, she could allude to the past benefits of cooperation. That would be cool.
