If you're playing a Druid but only play Feral, I'm sorry, you're doing it wrong. if you wanna purely play energy-combo-based DPS, roll Rogue. You don't roll druid to play only 25% of the class. Waste of a Druid toon. At the very LEAST you should be comfortable in 1 more spec (usually Guardian, since back in the day Bear and Cat were the same spec, Feral, with minor talent-point differences, and minor gear differences). On the flipside, Moonkins can usually heal, and Restos can usually shoot lazers, since they both gather caster gear (again, with differences).
The whole point of being a Druid is having access to all 4 roles the game has to offer (Tank, ranged DPS, melee DPS, healer). By choosing to limit yourself to 1/4, you're severely limiting your progress as a Druid and as a player.
