Honestly, the whole "people are going to be abusing jumping" argument is pointless. I'm pretty sure it won't be as rampant as people are making it out to be. Sure, you may get one or two people here or there that feel the need to jump up and down for a while, but it definitely won't be the "omg jump party at 5!" disaster that people are crying out about. Every other MMO has had that ability, and it was never a problem for them either.

The whole "realism" argument is moot as well. Final Fantasy is as distant from reality as can possibly be. I mean, fantasy (it's even in the game's title) pretty much means "the opposite of reality" or "not realistic." Yeah, the graphics are good, probably the best for any other MMO out there, but graphics do not equal realistic. I mean, the sky is literally falling in this game, for pete's sake.
