Highly doubtful. At most it’ll be a subsect of them that realizes their zealotry has gone way too far and that the radical light is just as evil as the void and that small sect is what helps us.
I think it is pretty clear that at some point we’re going to have a light vs void or at least a light vs us expansion or at least a narrative focus. Even other major games have had their own versions of a tyrannical light as a foe and WoW has long since established that while we definitely view the light as a positive/favorable entity over fel, necromancy, and/or the void, it absolutely can be used and seen as bad while the “bad” can have elements of good.
Plus given the current political landscape…having a bunch of supremacists bolstered by figureheads who send them to go to war against “lesser/inferior” beings is easy to write for.
