Mob flurries a lot, would have killed my group if we didn't get it slowed. 75 cleric, 77 monk, 80 pally, 75 shaman, another 70 some pally dpsing
Not sure if it was totally slowable, damage output was still really high. Not a ton of hitpoints though. If you can kill the other mobs in there, you can probably kill this guy.
Also a note: He spawns on a spot that does not normally have a mob. A zonewide emote goes off when he spawns, too.
Also note: Expect this is the only year we'll see him.
