mana sping isnt bad, but it doesnt stack or scale with healing gear like the healing totem does.
but then look at the water shield changes in 2.4
Water Shield now restores mana periodically regardless of how many charges remain. Duration increased to 10 minutes. (New Version - The caster is surrounded by 3 globes of water, granting 50 mana per 5 sec. When a spell, melee or ranged attack hits the caster, 200 mana is restored to the caster. This expends one water globe. Only one globe will activate every few seconds. Lasts 10 min. Only one Elemental Shield can be active on the Shaman at any one time.)
