Thing is, at 70 (or maybe even at 80, don't remember) you got to choose between "max" DPS or Mana Regen.
You can't put out the best DPS and have the best mana return, so you'll have to sacrifice some DPS talents (say Imp. Insect Swarm/Moonkin Form) in order to get OoC.
Of course you'll have to put enough talent points to get to E&M which I think is important.

I removed 3 points from
Celestial Focus and put them into
Master Shapeshifter and
Omen of Clarity.
More spell damage is always good and OOC is great now that it procs off spells.
It actually procs of making bandages too !
