Quote:Question: Can you stack effects from the same "element" with multiple shaman?
Yes.
Quote:Can you get Windfury and Tranquil Air, and Grace of Air with two shamans in a group?
With three shamans yes, two shamans no (all three are air totems).
Quote:The effects of individual totems outclasses the effects of blessings.
Total them up and see... I'm not so sure, but maybe I haven't thought about it long enough. TA < BoS always, SoE + GoA + WF > BoK + BoM for melee DPS but not by a huge amount... or is it? Mana spring + mana tide < BoW + JoW.
Couple that with the continuing mana cost, limited life span, and immobility and I still don't see it approaching what the paladin can do.
I believe the game code doesn't support it well. There are no friendly effects that are AoE based to my knowledge, they are all party-based (with a range). Seems a trivial thing to add but who knows how their code works.
edit: Thought about it some more... with paladins you only get one per pally. With shamans with "raid totems" you could get 4 per shaman, one earth, one fire, one air, and one water. Even so... not sure it'd be overpowered.
