I had 2 batches of Mage + Shaman which I was power levelling with my 70 prot Pally.

Then I decided I want a 3rd shaman in my 4-box just 2 Sunday ago, he was lagging behind in xp.

When the 3rd shaman hit 55, I went to Hellfire. The xp was so-so.
I cleared Blood Furnace 2 times. and I got my 2x Mage + 2x Shaman all to 60, and my 3rd shaman was barely 56.

So I decided to go back to LBRS grind, and when I hit level 57.80%, I went back to clear Blood Furnace and cleared it 2 more times.
After I hit 58.5, I started doing Hellfire Quests.

After I completed the dreadful "Collect 12 Blood Boiling" on 3 shamans, I got him to 59.90 with a quest to turn in the Apothecary.

The upgrades are very nice, and I plan to just plow thru the quests that offer immediate upgrades. I think I will be honored in Thrallmar after I complete the 2 instance quests. I then plan to grind Zangarmarsh and Coilfang instance until honored.

Then Terrokar and Auch for Lower City reps until level 65 and honored.
