Talents:
Get Maul + Grab r3 + Chain Lightning r3 + Unity with Nature r3. You can lower your Vibrant Health, Heling Burst and Renew to r2.
Rubies:
Natural Rage is really bad. You can remove it completly (it's better to go through Call of the Wild).
Master of the Storm are "must have" rubies.
Nature's Grip is great however r1 is enough.
The build I'm using currently (on p2p server):
