The Winter Wolves act in concert with the Ulricans for basic hammer-and-anvil tactics. The demigryph knights are more independent, charging at vulnerabilities when the opportunity arises and counter-charging enemy monsters for glory.
Hmm, seems the Winter Wolves make slightly better use of Seija while the murderchickens uses Esbern better, but neither being particularly advantaged.
Bullshit.
I started reading this quest late and that vote was over before I got here, but Mathilde going full anti-Sigmar is definitively not the route I would have supported. It might make sense on an emotional gut level, but the fact that she has been part of a literal battlefield Miracle of Sigmar always made the whole thing seem like a petulant "Well, what have you done for me lately?"
Dude, we were picking types of horrible trauma to get. She's not supposed to be rational about it and we're not supposed to enjoy it.
From Mathilde's PoV, the Church of Sigmar has been nothing but an impediment, despite the best efforts of its adherents.
