I love how people have already forgotten that the devs have already ruled out Blue Mage because they feel that the inherent mechanics for that class clash completely with the style of play that FFXIV requires, skills based vs gear based basically.

I would personally love to see something like WoW's Druids placed in this game, the ability to shapeshift and gain abilities based upon the form you take would be a nice switch from the other classes at this point.
