To be frank, no one knows if it is or it isn't innovative just yet. In the same vein as people calling BLU worthless the opposite end lauding it as innovative is well wrong. Based on the information we have the approach is certainly different in the context of FF14. In the grand scheme of MMOs? I wouldn't say it is 100% innovative... but the, currently on paper, the idea of MMOs having a traditional trinity balanced set of classes accomplishing one set of endgame goals and having a differently balanced set of classes accomplishing a separate set of endgame goals is a first. Most MMOs do a type of mmo only (theme park or sandbox) and balance their classes against that type. FF14 will be the 1st theme park mmo to have 2 sets of balances that don't intersect at endgame.
