I think at this point that if we want to get rid of Disdain for Sigmar, it might have to be by having us explicitly hang out with Sigmarites enough that Mathilde gets to reprocess her dislike for him and finds more worth in him.
If we had the time and will for it, that'd probably mean trying to make inroads with the Witch Hunters by volunteering our expertise. Witch Hunters don't typically like to receive help from wizards, but they might make an exception for this one, given her history.
Just hanging out with Sigmarites wouldn't do anything. Mathilde agrees there's plenty of cool Sigmarites. In fact, that's part of the issue! It's not just an asshole god for assholes. It's an unworthy god with worthy followers, and those worthy followers should be encouraged to find a worthy god.
Anything that would mitigate it would require Sigmar to proof himself worthy after all. Doesn't have to be by helping Mathilde, mind, and in fact that would probably be better. But something like the the Mork heist, Khornate fisticuffs (though something appropriately foreign to Sigmar, like, emergency paperwork help), or even the bearican.
Come to think of it, that Ranald is so Ride Or Die with her probably doesn't help. Mathilde has Standards for Proper Gods.
It's precisely because it's not 'neutralizing an existing trait' anymore. It's a genuine path we could go down with its own merits. Mathilde reconciling with Sigmar doesn't bring us up to 'normal', it reopens a connection between Mathilde and an extremely significant spiritual being. Mathilde already had his favor -- in a world of 'touching a god's power might produce dhar' rulings Mathilde was comboing off of his light like a finishing move in a video game.
He was there. We were the one who left.
If we want 'a scene where Sigmar reaches out' before we're willing to vote for that scene we're probably putting the cart before the horse. I recall a certain Chaos Warrior with a similar desire.
(I guess I'll just sort of wave to the plan writers for ideas about how to get voting for it, though. This'll be a few months.)
Thing is, I'm not hardcore on keeping the trait, because it's stopped being relevant for a very long time. It was a really interesting facet of her character, and for the first while I didn't
want to lose it.
I'm not saying there's nothing uniquely interesting about Sigmar. I'm saying we're at the buffet, with tons of different foods, some delicious looking but untried, others tested and confirmed great, and you're saying you want to pay the price to special order a new dish. OK, we can do that in principle. But you
must explain why you think that particular dish is going to be so great that we
need to special order it. And I'm gonna be honest, I haven't seen it.
Like, "River Ambush" has been sitting under the heat lamps for
hours, and I keep promising myself I'll eat it next round, but then the cook brings out some new creation of "Silk" and "Orbs" and "Treehouse", and fuck me if that doesn't look stunning, and we're back to full and waiting on the next round, with dread and despair because there's just too much delicious and we finite being cannot take in the totallity of all possible existences.
I also want to point out you're misunderstanding the divine power and winds produce dhar thing. Using them together is not the issue. She has done that since, see the giant hellflame tower. It's channeling it in the same soul. She could get a temporary blessing, like from Ulric and Taal when hunting Alberich, but she's never going to cast those.
Sigmarites are generally closed minded and prejudiced on 'screen'. I'm happy to have a trait that's basically 'justify your nonsense' and treats Sigmar like any other god in the empire; regardless of power, evaluated on what the followers do.
It's okay to be antagonistic to people who literally shut doors in your face.
On the other hand, that's also unfair. Kasimir is awesome, and quite open minded. And we've known and met quite a few cool Sigmarites. In fact, there's been one real asshole Sigmarite we interacted briefly with way, way back when Abelhelm was alive, Roswita's priest was kind of ineffective, and the Grand Theogonist is a politicking bastard. But let's note that the Ar-Ulric is also a right bastard when it benefits him, being willing to wipe out an entire countryside, and the cult is having an internal battle over the supremicism of the main branch.
