Fair amount of extra HP, +15 to Herbalism, and 10 points of Nature resistance. War stomp would be nice for adding some stuns to some mobs, but bear in mind its subject to diminishing returns. My advise? Tauren Druid, Orc Shamans. Blood Fury gives you a massive increase in DPS for a short time, the sort of burst you need when in a big fight. War Stomp isn't effective against bosses, whereas 4x Blood Fury gives you an excellent increase in DPS which you might need to burn some bosses down. Plus with War stomp you need to be within 8 yards. The shammies would be best off laying down a few totems near the Tank and then retreating to a safe distance to do the bulk of their DPS.
