There are much better quest opportunities at the
Level 62-63: You will only be spending a little bit of time here in Zangarmarsh. Start by loading up on quests at Cenarion Refuge at 78, 65, Nearly all of them will keep you wow gold in the eastern part of the marsh but there are much better quest opportunities at the Draenei base further north. Once you have finished up the easy quests here head north up the road to Telredor at 66, 50.
Ride the elevator to the top and load up on the entire quest here. There are so many you will definitely want to set your hearthstone here and once you are finished you should be very close to level sixty three.
Head west across the zone till you find a small Cenarion outpost. There is only one quest giver here, but she directs you to an area that raises your rep with Sporeggar. Kill the giants and collect spore pods until you reach friendly with Sporeggar and there head to their main town for a few more quests.
I personally found little use for Sporeggar so if you are past 63 already you can skip this part. What ever your decision, head next to Orebor Harborage at 22, 64. When you have finished up the few quests here you should definitely be over 63 and can leave the marsh.
The ten levels you spend in Outland are very different from your previous ten. The biggest change is that you don’t have to grind as much and most of your experience will come from quests. Each zone has at least five different quest hubs, some in very remote or hidden locations.
