Blazing Swamp isn't actually that bad. You get reagent boxes, which can get you quite a few of the reagents necessary for both the subclass quest and the noblesse quest. It's generally a lot easier to get a spot in BS than to get one of the good spots in FoTD.
If you have SH/SE, consider moving to Ketras/Varkas at 74. You'll need to be level 2 alliance to get your third class change done. I did these places with SH/SE & EE out of party. You run out of mana quickly, but you (sometimes) end up with nice S grade armor recipes if you can stick with it long enough.
A lot of times, good xp isn't about how uber the spot is.. it's more about being able to log in and not have to spend 15 minutes looking for an available "decent" spot.
