Depending on your class, this can either be an incredibly easy fight, or a difficult one.

I tried soloing him on my level 43 druid in cat form - I ran away at half my health because I hadn't made a dent in his life.

Tried it again in bear form (still level 43) and it was a piece of cake. It was tediously long, but there were no close calls. Every time I got low on health, I just rooted him and healed. Took me two roots.

For non healing classes, or classes without a near permanent CC (locks with fear, for example), this fight probably would be a pain in the ass.
