I would prefer it if they would not half ass it and just implement the job system and banish classes from existence. It would be necessary to let people class change once, or swap classes around once into something they're comfortable with.

My primary choice would be for them to not use the job system at all and only use the Armoury system but they've already strung the whole world along too far. So I hope they see that having a half assed character system is going to really hurt this game's appeal, no matter how hard they can convince themselves that it makes sense. I'm fairly certain that anyone taking an objective, fresh look at whatever they finally cook up will just conclude that it's a terrible system.

An example of half assing it: saying they're keeping classes but then reassigning some class actions. Say what?? It's like grafting a monkey head onto a cow. Just be done with it and put the class system out of it's misery.
