My druid spends most of it's time healing, but as far as I'm concerned the 2:1 Wrath/Starfire rotation works a treat. Unless your actually raiding and have enrage timers to worry about then you don't need to get the maximum DPS out of your team.

Course when I raid it's only on 1 toon as a Tankadin so perhaps that explains my lack of desire to min/max my DPS.
