You're the one being narrowminded. I'm not telling you to play this way and that - you're paying to play the game. But if you're just sticking to only one method of playing you're seriously being narrow minded about the many ways of playing a hybrid.

I don't like being a healer. I already have a paladin for that. But there are just times when you just need to heal, even as feral. An outdoor group quest for example. Take the ring of blood. You've got a good group of 5 people, but none are specced for tanking nor healing. Are you just going to wait for an hour waiting for a proper healer, or are you going to swallow your pride, put on your healing gear, and heal that fury warrior with a shield that's going to tank for you?

I'm not saying you have to. You have every right not to do so. But if you do, you're seriously showing a selfish and idiotic side of you to your group. It is an MMO game after all.

I've also said this before. All hybrids are fully capable of fulfilling whatever role the class is designed to fill, regardless of spec. Picking up a spec only allows you to improve on that particular role, but at its base you're still capable of doing everything else when neccessary.
