I believe this is too over power. The ability to change classes on the fly is unfair.
people should have to go to a spot (Mog house in ffxi) to change their job.

Can you see how someone can easily cheat the game by just changing jobs as they go?

To be honest i can't think of an example to show right now, but I remember in FFXi, I used to always say man only if i can change jobs right now.

does anyone see this from my point of view?

ps... also i can't see how classes wiith pet will come into play. with this job changing systems.
