I'm going to side with reality here and say that the class system is here to stay.

You may not like it, but them's the breaks. You're welcome not to play, or to invest a little faith in Yoshida and his team after all of his hard work and actually give him time to work this system into something better than what we had in 1.xx.

Personally, I don't expect the class/job system to be fully evolved in ARR and I don't really care. I enjoy the current system and I'm glad they have the groundwork to add more depth to it.

The one thing people don't realize that restricting it just the job system hamstrings the potential growth of this game. Instead of Job and Class quests it's just Job quests, instead of Job based items and roles and class based items and roles it's just one. You're narrowing your scope for the sake of being a unique little snowflake.

Any and all limitations by having a dual system like class and Job can be overcome by simply expanding on it. Issues with Dark Knight attached to Gladiator can be lifted by creating a secondary weapon type for each class (Greatsword for the case of Gladiator) and given that we wanted a diversified weapon system in this game, this fufills a request while adding further depth to the system as a whole.

In the end my plea is to give this guy some time. He just spent the entirety of two years making a game that should have taken him five, given the normally yield of games out of Square Enix's internal development. It's going to be vanilla version all over again so keep that in mind with the base systems.

So it's going to be a while before we see the fruits of this labor develop. For now, just think of the classes as sub-forms of the jobs and leave it be at that.
