Shaman Totems vs Paladin Blessings

[MongoJerry]

Minor nit: Pally resistance auras do not stack with Mark of the Wild or with the Priest buff Shadow Resistance. Therefore, the Shadow Resistance aura is rarely used and offers no benefit, since Priests tend to put Shadow Resistance on the whole raid for shadow-heavy encounters.

And Shaman have nature resistance totems that Alliance don't have -- but they are an air totem, which means no windfury, grace of air, or tranquility for the group. And like the shadow resistance aura, they don't stack with MotW or hunter aura. Basically, two equally useless auras.

Everything else you said, oldmandennis, is spot on, though.
