Stacking ToW would've been great...although to be fair...does sound a bit imba.

With water shield and one mana stream totem...I don't imagine mana will be too much of an issue....not when levelling anyway. In instances...if mana regen was an issue, I could always use the pally's BoW...but in saying that, I'd prob have one of the shaman resto...so would have mana tide.
