http://www.wowhead.com/?talent=MtorkiIsxuVoZxVcd I believe i came up / a good build for balance doomkin druid, thats half decent healing/offhealing in 5mans & raids.
I think the point in OOC is wasted, if you're healing you're probably not going to melee. The two points in Nature's Grasp are probably better used elswhere, since it's only useable outdoors. I'd take those three points and put them in Subtlety. If you want to keep OOC then take the point from Brambles.
