I've been running this combo and I really like it. I run Prot Pally / Dreamstate Druid (balance / resto hybrid). The druid is Dreamstate because I wanted more dps than full resto and the Dreamstate talent keeps me from running oom. After about level 35, you can handle tons of mobs at once. If you can sustain using Insect Swarm, you could cast it on every mob that the pally is tanking. It becomes even easier after you get Innervate and Hurricane. After you get Dreamstate and Moonkin form, I would suggest going down the resto tree for Intensity / more resto based talents.

Currently level 50 and its been a blast so far.
