Prot Pally vs. Druid World PVPFollow

So I'm a prot pally. When people around my level attack me I don't generally have much problems. Melee classes I kill in short order. Casters are long fights but I usually win once their mana and cooldowns are gone. Hunters I have some problems with, but hey, what are you gonna do. Druids, on the other hand, kill me everytime. They usually start the fight in feral form, and so I fight them as if I were fighting a rogue or a warrior. But then they stun me, go back to normal form, heal up, slap a few spells on me, and go feral again. They rarely run out of mana cause they spend most of their time in feral, but they can go caster just long enough to heal up. Any tips?

Sorry, just dinged 60.
