Good to know. Haven't been in there inawhile to see if there were any changes.
They no longer instakill if you use the wrong damage, but it's still a massive hit best avoided. Also, don't pull them too far apart or they won't merge.
So to start the fight, have your crusaders remove there weapon, and they take O.. and have your guard/zerker/monk tank K. The first pull or 2, you will most likely have people dieing to things, make sure to tell them that they need to pay attention to what they are casting, and if they get one shotted, not to use that again.
On pull, we pulled them to the back corner of the room so they were in range of the snow banks, we had casters and melee burn them both to 80%. Then burn to 77, then work to 75, they need to get at 75% within 1% of each other, or they will heal back tup 100. As soon as they merge, everyone needs to click the snowbank, and then throw snowballs at the named. You cant do anything else to the named. Any spell or melee attack will kill you, so basically your healers will have to heal threw the named as it runs aroudn trying to kill people, thats why you have to be fast with the snowballs. After enough people do it, he will become immune to anymore snowballs, when this happens, have the tanks get rdy, he is about to unsplit.. Pick up your mob, and repeat. Tell everyone to hotbar their snowballs. You get 5 snowballs per click, and you can harvest multiples, and they dont depop if you wipe. So make sure everyone gets enough for the whole fight the first time, 2 harvests would work.
After everyone has snowballs, and they are split back out, start moving them across the room. You now need to setup the raid near the Right thrown(if you are looking at the throwns). You will be able to see an axe sitting on the thrown. when they merge at 10% you first have to snowball them, then use the axe on them.. they will NOT SPLIT OUT, you just have to watch its buffs, and as soon as they drop the blue hand buffs, you burn it to zero.
Just a tiny bit more information. The snow banks are along the sides of the room and the axe is sitting on the southern ice throne.
