I don't know the horde quests well enough to be able to chain effectivly. My XP per hour will definatly be better just by grinding. I have a few 60s and high 50s on my old server so I know how and where to grind post 40.
I only plan on doing the quests for items that I want. I'll make a run thru SM and pick up the quest sword, ill make a run thru RFD and get a vanqisher sword. I am not too worried about items, I can PvE fine with BoE blues and greens.
K_A is right about the badlands though. Mad cash from grinding the lesser rock elementals that are lvl 37-39 and then the regular rock elementals that are like 39-41 or 42 I believe. The only problem is this spot is heavily farmed at times. I got lucky and had no problems.
Combat Swords spec. I am starting with combat till 40 then moving on to assassination past lvl40.
