Frozen Statue of the Snowbeast is a relatively easy mob once you have the strategy down.
Everyone enter the room, tank him wherever you choose, although an open area is usually best due to his memwipe. Depending on how many tanks you have in your raid, assign 1-2 tanks to the named. The named will memwipe about every 15-30 seconds (unconfirmed) he emotes white chat text before he does so. The memwipe drops the current tank to the bottom of the hate list.
The fight is a straight burn fight until the mob reaches 0%, at which time he will fall down. The snowbeast can still move and such so we kept a tank on the snow beast to grab aggro if he stood up.
When the snowbeast falls down, two adds will spawn that are blobs. They are x4 adds. They MUST be tanked by separate tanks. If they both attack the same tank, they will kill the tank (one shot) and heal the named 50%. The snowbeast will stand up and you will have to DPS him down to 0% and then redo the adds again.
If done correctly, you should have one tank on each add and a MA to designate which add to burn first. Burn one then the other. The named will then stand up with 25% health. A good idea is to separate the adds a bit so if you have an aoe tank, they don't grab aggro off the other.
DPS him down to 0% again, and 3 adds will spawn. Same idea, one ad per tank, dps each one. It seemed the 3 adds had less hit points than the first 2. Once these 3 adds are down the mob dies and enjoy your loots.
