This is an interesting Theory Build.... However, I can't help but think that for DPS, you would be better served to utilize Avatar of Nature because they get an additional x1 to their critical multiplier. If you're using dual balizardes, you're looking at 30% chance to land a critical at a x4 multiplier (not counting additional multipliers coming from Paladin Smites). The Wood-woad form adds a nice chunk of damage (as well as boosts to your constitution and strength), and if you're casting buffs often, you will find that maintaining spirit points is rather sustainable. Though you would end up probably needing to twist Sense Weakness, primal scream, and one other (I personally would recommend Endless Faith for unlimited mana - this is particularly nice for Bladeforged varients who use the Reconstruct SLA).
Just my 10 cents. >.>
