Start at Stranglethorn Vale. Quest stacking here is also important if you do not want to go to the northern end of the zone, to do tasks 1-2 and then go back at Booty Bay. You can do Rebel Camp’s quests first, they are largely independent of the rest. Then, go to Booty Bay and you can pick up two main quests for the northern Zone: the start of the Excelsior chain and Investigate the Camp, both of which takes you to Nesingwary’s Expedition, where you get all of the nice happy quests there.
You should go to Hillsbrad at least level 33, and then you can actually complete all of the quests that you could get at level 30… There is only 1 or 2 quests that you can actually complete at Arathi now.
