I know you can change at any time. My point is he doesn't have the time to keep trying all the classes until he finds something he likes. Between IRL obligations and already being a vet from another MMO, he's having a poor experience in XIV because he's not sure what he wants to do and can only play an hour or two a night, but the class he thought he'd like at the start isn't working out for him. He just wishes he could try everything at Max level and settle on one thing to play instead of taking a crap shoot from level one every time. I think it'd be a helpful feature for newbies and vets alike to see what they are in for and ease some of the frustration for those on a time limit.
