Information:
Level 62 NightElf Hunter, Beast Mastery Spec'd (52/0/1). I was able to solo this quest without any problems whatsoever. Only buffs used were:

• Spirit Bond
  
• Aspect of the Hawk
  

Pet Buffs:

• Spirit Bond
  
• Intimidation
  
• Bestial Wrath
  

Auto-Shot and Serpent Sting(s) is the only Ranged Damage dealt; Mend Pet(s), Bestial Wrath(s), and Intimidation(s) took the remaining mana pool.

Note:
I've seen him as a 62 Elite and a 63 Elite.

Good Luck! :-)
