There's this achivement in retail "Two sides of the tale" which rewards a mount. Currently working on alliance side of the quest. So the waycrest manor quest can't be turned in to npc because I didn't complete the Drustvar storyline and npc is phased out.. Oh well- I have to do the drustvar story then I thought. Got to the quest "charming the lifeless" which is guess what - not possible to get because there's a naga world quest active in the area so I can't pick up the freaking thing. I have to wait for the world q to end.
Classic quests might be tedious to a point. But retail quests are freaking ridiculous. I'd rather do classic qs any day, phasing sucks.
