Ziglark Whisperwing HP
 

it seems like every site lists ziggys HP at 2k, this would make sense for a mob of his level... (granted these different sites could all be using the same info)

but when i ran in there with my bard i was curious if i could charm a mob and solo him... 20 min later i was so bored i left.

I came back with a ranger and took pics which show me reaching 2khp in damage long before he starts to cast heal or loh or whatever it is that he casts.

Sorry I was being hyperbolic when i said 20 min... still too long though
