Clean up easy green kill quests in STV & Badlands.. start work in Tanaris & Feralas.. I ran Uldaman quite a few times in the low 40's. No Un'Goro on that list?.. I like that area since the collection quests have frequent drops and tie in so well with the kill quests.
Thanks. I'm tempted to drop out of SM now (again, 37 atm) and group my four, have my booster follow ungrouped, and start questing. Think I'd run myself dry through your list before 45?

Feel free to add to the thread I linked. I see it as the beginning of a quasi-leveling guide for boxers. Others have alluded to it, but we really should start some sort of inventory and progression of kill quests (or at least boxer friendly quests).
