"Specialists are what happens if you practice a specific genre of thing. You can sort of wear a groove into your momentum. It doesn't fade for that thing as fast. So you get healers, I followed healers around a little doing what I could but I needed to go do other stuff after an hour or three every day, who can work most days but sleep in or skip a day or two if they want, and they'll still be about normal levels when they come back in. They're not as fast as a high momentum sorcerer but they're comparable to a low- or mid-level flier like me in their specialty."
