Wow is too easy.. at least when you think of having a one character type of gameplay like FFXI supports.
I think most of us want to keep the job-switching mechanisms from FFXI, and most of us are happy that community and real world reputation plays a factor in how people percieve your character. FFXI was unlike almost every other MMO in that you gained the most benefit by picking one character and playing it, whereas many other MMOs require you to switch between completely different characters (and thus online identities) in order to play in a different role.
Given that: WoW and its system of constant patching and abandoning older content for newer content would simply make the game unplayable if you were able to swap classes with the same character. It would be so easy and repetitive that one would quickly tire of the game playing through it with 'merits' and already earned equipment.
It is simply put: too easy of a game to have the option of swapping classes/jobs.
I personally like having just ONE main character in a Final Fantasy MMO, that gives me a feeling that my avatar is truly a part of the gameworld, and not just a throwaway alt that I bring out in certain situations.
I LIKE having my actions actually build up a reputation for myself (either bad or good) because I can't just run away to another alt every time I ninja an item or raise some newbie. Longtime FFXI players know what I mean, any other MMO player doesn't.
So before we start saying 'Hey, I like this idea from WOW', or 'WoW did blahblahblah better', or 'Man I wish I had XXX from XXMMO'.... please remember that there was nothing as unique as the single character system that FFXI created.
And alot of systems from other MMOs would simply be crap if they provided for a single character that could serve as your avatar throughout years of gameplay.
