With dual spec down to 100g, you can have feral/moonkin main and moonkin/feral slave team.
Unless you are main healer for raid, you really dont have to spec and gear restore. As long as your moonkin slave gear have a big enough mana pool and spell power, you can heal most 5 man.

If and when LFG que is too long a wait for a healer and tank, you can do that yourself. The options of cat/cat, cat/moonkin, moonkin are fun.

5 druid stealth runs are the most fun.
