I have had so much fun with this boss when farming for the viper set.
That new AOE damange of the boss is hilarious. Me being the tank and warning every time to dodge the AOE in advance...
But it would always be the same result: the boss does his first AOE and boom, almost every time (!) 1-3 people dead on the floor :-D
Still not a single wipe though. Just annoying to res the people with the boss on your back.
