Went out there to look for a quest to do so I could get the achievement and found nothing but a quest to take me to Blasted Lands and a cooking quest, neither of which count towards the achievement.
Anyway to know what quests I have and haven't done without using an add on? Last time I tried EveryQuest it was telling me I didn't do quests that I clearly remembered doing, so it was more of a headache than a helpful tool.
And do the raid quests count towards it? Pretty sure I did all of the raid quests EXCEPT the Eye of C'Thun, which I had but never got around to turning in before my sub went up and it either disappeared from my inventory or I accidentally deleted it. I really don't feel like getting a group together to get past the Twins again, so I'm hoping that isn't the quest I need. :/
