Sure enough, I forgot something.
• Quest Instructions. One of my favorite new addons this year was Lightheaded, because it gathered up Wowhead entries' comments and made them available next to the quest log. Coordinates, special advice, it's all there in Lightheaded. One of my greatest pleasures in addon management this week was going ahead and turning it off because I didn't need it. The clarity and completeness of quest texts has really improved in Lich King. I've needed to go look up something on Wowhead...twice? Maybe three times now. With hundreds of quest done, that's an awfully good success rate, I figure. NPCs describe the position of things, assets you'll need to have along, and tricky complications to be aware of in pretty full, useful language.
