The kill tasks are fine, but I don't see much in the way of quests, but is there a mob/dungeon progression that cuts down on the running around in circles, searching for a yellow mob.
Spec is the question though ha. Summ is good for solo just a little boring (tip: when you cast your damage shield on your pet you cant move or cast - if you do it drops) and Supp is good for groups with pbaoe. Darkness is a mix!
