Update 2: Wow wow wow... I dinged 62 today and gave it another shot. 100% easier. No wipes. First boss downed with no deaths. Total 2 deaths in party from trash (and sloppily not healing). 2nd boss fell easy as per usual. On last boss followed tips here and pulled the guards back so that the boss-man didn't aggro me. Took nazan down to 33% while he flew around using grounding totems for his fireballs. He descended and came at me... died easily (though his breath hurt). The boss-man was soo easy after that.

So, record for me: Full clear of Ramps, no wipes, lvl 62.
