The game needs a bit of breaking, honestly. The way the game currently, the only thing separating one player from another is gear. That's fine as one element to differentiating a player but it's bad as the only one. The game needs more wiggly room to make it interesting and they have the base for it. They just need to do something about it.
Not to mention that gear is also incredibly boring. No interesting sub stats, proc effects, set bonuses etc.
I really hope Square takes a strong look at character customization and gear itemization for the existing classes before they start pumping out a whole bunch of new jobs.
