It's pretty hard to make old nukes strong nowadays because of all the fucking unpiercable DR. They'd have to come in heavy with the refine to make Brave Gullveig usable again. They could also make her give out some buffs or debuffs, like how Katarina got Share Spoils, but Gullveig isn't the debuffing type.

though they'll probably just slap 1 extra action on her and call it a day.

I remember Plumeria and Gullveig being besties. Can't do that shit anymore with all the anti warp skills.
