I honestly don't understand why every Christmas Boss on Lordaeron is Overpowered and almost impossible to do.
If on Icecrown Realm, 40 people with BiS gear, Shadowmournes, RS 25HC trinkets etc. have trouble downing him, what can we expect on Lordaeron?
Nobody says that it should be just a tank-and-spank giveaway-loot fight...
But for the love of God, do something about the Grich, so that it can be killed by multiple raids.
In my opinion, this should be a fun event for all, not a Gear Check fight.
