70 balance druid; most annoying thing about soloing him was repeatedly shifting back to caster form to undo his dot poison bolt, which is very nasty, wasted a lot of mana.  With 10.6k armor (moonkin) he was still hitting for 1500 sometimes.  Didn't do any kiting, just stood and fought him in place, using over 15k mana including 1 mana pot and innervate.  Actually wanted Band of Hierophant for an alt, got Orb of Deception instead (didn't even remember it existed until it dropped).  Can't complain.  He's a tougher kill than some 70 elites.  Immune to CC.  70k health on him seems about right.
