I have, I also read where Yoshi stated himself a lot of the updates we got even when he took over was stuff the previous (Tanaka) had in line for XIV, his work was starting around the Job system introduction and later.

Also no, they're not the worse design in MMO history because it was actually pretty innovative to not be locked to 1 Profession per Character. I don't agree with weapon = class for obvious reasons, but being able to do everything n 1 character is far from a bad idea unless you really do enjoy shitty MMOs.

The MWs were just lacking features (that they're adding and have been adding), otherwise it's not the idea, it is indeed the implementation.
