Hey everyone, this is producer/director Yoshida.
I seem to recall there being a discussion about what each class will become job-wise in a previous thread. While it's still a bit too early to talk about the specifics, I will let you know a bit about the plan. Once it becomes possible to publicize the specs, I plan on making a post in battle mechanics section, but since job implementation will be taking place post-class balance adjustments, it is going to take some time.
(Planning for post patch 1.20.)
Matsui, Gondai, and myself, are creating this plan, and the early jobs are based on "party balance."
