Im alliance and I did all pertainable quests at lvl and even went back in Wrath to finish it up, I am 3 quests shy of the achieve and I cant for the life of me find the remaining ones!!! I even killed 5 of EVERY type of mob to see if they had a drop quest, I searched every nook and cranny for a quest, I even camped rares / named mobs for quests!! Any suggestions on where you found that last quests? Or quests that start in other zones. The only place I havent done in outland yet is Shadowmoon valley but i cant see any quests starting there.
Your help is appreciated!
