Thanks a lot for all of the replies.
I'm leaning towards Black Mage now, I have a soft spot for mages, plus they looked really cool in some videos I was watching. I'm really used to those action combat MMOs, even though as a lazy ranged dps, I just stood around and dps'd, so no matter which class I pick, it's going to take a lot of getting used to. At least this isn't like the games I was previously playing so I'm not locked into one class. :3
