I took this guy out pretty easily with my 54 druid. Only resisted root once and all dots held, the only thing he casted was "Mastruq Bellow" which had a fear icon but did not do anyhitng noticable.
Took malos to slow (resisted without, unsure if it was just a fluke) but after malos didn't resist anything. Didn't hit that hard, 50s to mid 100s mostly, but proc'd something hardcore
