I keep seeing posts about why certain characters don't deserve a redemption arc, so my question in: Who does?
Personally, if we absolutely need to have these stories told in Shadowlands, I'd love to see one for Neltharion the Earth-Warder. I was saddened that he was only mentioned in passing during N'zoth's actual appearance, given the gravity of the Old God's influence on events involving him for the past 10,000 years or so.
