One of the biggest setbacks to druid FCing, is the fact that Resto becomes the more viable spec due to increased stamina in bear form, swiftmend, and the ability to root break from shifting. The other part is the lack of health pool. A good prot FC can reach about 4k hp buffed @ 29. It's incredibly difficult for a druid to get even close.
If you're trying to figure out what to do with a 29 druid, you can always play as feral DPS, boomkin, or even resto druid healing. I'd be curious to see a druid FC, but not surprised if it doesn't work out.
