the more i think about this, the more i like beacon of light, this could be a lost stronger than 2 resto shaman. I'd have to crunch some numbers and see how scaling works and whatnot.

I'd be concerned about backup dps.

Atm, my two resto shaman totems heal between 1900-2100 per tick (total) depending on the character. So a lot of random small aoe can be ignored if it isn't persistent. This frees them up to spam a lot of lightning bolts.

I have noticed that just 2 dps makes killing things fast an issue. The adds on the last stone core boss and the adds on the last grim batol boss are a lot harder without a 3rd dps.

On the other hand, the paladin's seem more efficient on healing, so if you never die . . . you never die.

Very nice theorycrafting.
