It's still a quest just about every class that can wield two-handed is thinking about. We've featured a video showing off this stretch of the Shadowmourne questline before, the bit where you retrieve Light's Vengeance, but I would hardly call The Sacred and the Corrupt old news. If you don't want to be spoiled, do not read/watch. Be warned: This post, as well as the video above, includes minor spoilers for Patch 3.3's Shadowmourne quest chain.
