If there is a job that can do anything

[Bobs]

First of all, I am Japanese. For that reason, please forgive me that I am not good at English.
If there is a role to eliminate the concept of "role" and to be able to turn around to almighty, would you approve of having such a role? Is it the opposite?

If I say somewhat, it is the opposite.
Because I thought that gameplay named role playing would be diminished.

Final Fantasy 11 would fit this description more. In FF11 you have sub jobs that can change the main job's role.
In Final Fantasy 14 they have limited that and instead gone with a more ridged system with a 3 role design.

Over time is has just become more ridged.
