If your guild has been struggling throughout the various bosses in Icecrown Citadel, then struggle no more! Icecrown Citadel raid buffs are now live. For the Alliance, it is called Strength of Wrynn
and the Horde version of the buff is Hellscream's Warsong
. For now, your health, healing done, and damage done are increased by 5%. It looks like it'll eventually cap out and end at 30%
but who knows when that will be. All in all, the buffs will definitely help progression raids out. If your raid doesn't need the buffs, you can simply talk to your faction guy and tell him to go away. He'll ask you once just to confirm, but if you are sure, he'll disappear. We've known that the raid wide buffs would appear at some point
but not exactly when.
