Was it necessary? Was it really helpful? You saved a pair of nukes and bomb heals for your mages. Great. Such a big deal. Nothing even close to protection auras being extremely useful. Anything else has its chance of being a bit useful in some specific circumstances, like hunting some specific boss with specific type of damage. Rare occasions are rare. Just this week teams I participated in used: War cry for 4 tanks. Stamina regen for tanks. Sap regen for mage pod. Antimagic for boss mob effect. Antiranged for boss mob effect. HP Balance for team. Shield for the mage that had non-tauntable aggro.
