For me, it's been tanking. I've always kind of wanted to tank as a bear. It looks so awesome, but no one ever gave me a chance. The three times I can remember tanking are as follows:
I was spec'd feral and running Sunken Temple. I wasn't the tank; a paladin was. However, this was before all the nifty treats paladins received for tanking, and it was difficult for him to hold aggro. My first reaction for when the mob ran to the healer was to shift to bear and taunt it off. This caused me to receive the most surprising temper tantrum from the paladin, who was intensely pissed off I would even dare offtank (as this meant he was not doing his job as main tank) and I, therefore, stopped. Thankfully the priest never died.
My only two others were with friends who couldn't be convinced that I needed them to not mess around because I had no idea what I was doing. But they didn't listen and it stressed me out to no end, so I set up my bear bars for resto PvP and haven't looked back.
Now, with dual specs coming out, I'm preparing a feral set. I want to try tanking again, and I've made friends agree to not go overboard and let me get a feel for it. I'm excited; it should be something new and fun. Resto will always be my main spec, and something I love, but there's a lot to be said for being able to try new things without completely screwing up your action bars or feeling like it's a waste of money.
Has anyone else been looking forward to dual specs (or even something else) to give them the chance at doing something they've always been locked out of?
