I liked the sphere grid system from X better. It allowed a little more freedom of movement/development. As for names... I dunno if we really need them. I'm against specialist jobs and sub jobs in general. As a GW player I liked to be able to define my class more by skillset than anything else. When I'm a W/mo I can either be a pure warrior, a warrior with heals, a warrior with protection skills, or a warrior with magical holy attacks. Not that I would do a lot of those things, but there's that flexibility. If I were to be given a paladin class, I'd wind up with a tanker, and tanking sucks.

If people want more uniqueness, then we need a more flexible class system and I don't see that happening if you add the old class names for the point of adding old classes to the game.
