Now, I like the Old God plotlines, really, because there's so much ambiguity about whether they're good for, bad for, or just there with regards to Azeroth. But four out of five expansions?
- Vanilla WoW: C'Thun
- Burning Crusade: Woohoo Outland! Sticking it to the Legion!
- Wrath of the Lich King: Yogg-Saron
- Cataclysm: N'Zoth, though we never confront ... him? it? directly
- Mists of Pandaria: Y'Shaarj
You know what? I think we're due for another Burning Legion expansion.
