yeah ramps was a b!tch, i of course had my epic geared main shammy to run my instances with, so im not saying it will work the same for you, but underbog is by far easier than slave pens, smaller groups, and less fearing/cc.

i also had an ele for boss tanking, and heroism, so im not saying its going to be easy for you, but the best course is instance till honored then quests.

also mana tombs was ridiculously easy, compared to earlier instances, last boss was mildly hard, first boss mildly, hardest part of the instance was the nexus stalkers, they need to go down first and fast.
