Ah good catch. I still think it is VERY useful for pve. Take Heroic Halls of Lightning boss Ionar, for example. You have to run away from him everytime he disperses. Now those little bastards put out a crap ton of AE damage and you have to run away from it. Most of the time you will take damage, even if prepared to run away. Popping this everytime he disperses will ensure that 40% damage will not hit your group for 5 disperses. That, I believe, would make him in the "doable" category. There are other bosses that put out massive AE damage too, Skadi is another example. His WW melee is devastating to a team that is all melee. I would put in the "not doable" category for any other all melee team. Paladins he might be possible with the above trick.

Only problem with this strat is, if they havent changed it, Divine Shield kills all your buffs. That sucks and reduces your teams dps as they round robin use it. Oh well, guess you cant have everything.


edit: hmm maybe on Ionar running them all in different directions and healing would be a better approach.
