Lost 2 dps wiithin the first 40 seconds of that fight. so it was me, the pally tank, and a warrior. And we killed him. took a while. but when people actually go after the purple orbs. Including tank. He is pretty easy to heal.
Those orbs are the hard thing. He is a very easy boss when your not being yanked around wildly. And people not standing in the purple ring. think your safe inside of it. And if your ranged, you shouldn't be close enough to be hit by it... But many still think a healer can heal through 60k or more damage to you a second. Or whatever it is. It hurts and you die if you no move.
the boss before him. He sucks if your all close and you aoe the adds. Really damage isn't too high. So healer can help kill them one at a time. Priests have a very nifty aoe cc for the fight. but if you have 3 of em by the boss and decide to kill em all at once. they do 50k to everyone on death. So spreading out is key. Even if on a triage around the boss. Ranged can split to killing adds and boss. Can't say for heroic yet except spikes doing a lot more damage, and his swirly move that does nothing to do damage I notice.
But taran Zhu isn't all that bad if dps can switch targets. Or if a beast master hunter whips out a turtle. That thing lived so much easier than the tank. And actually we did a lot better with it as the tank than our actual one.
