Bye Bye Tanaka

[Elexia]

I get that, but he left a long time ago, so hence why I dont get.

And I do think it was Tanaka's fault, not that "the game was rushed out"

Yep, you've definitely never stepped into the business world.

Tanaka wanted Fatigue, Physical Level, and many more systems

He was also the one who originally stated XIV would have no levels, once again if you've actually stepped into the business world you should know how easily and often higher ups interfere and change things, look at what happened with Mass Effect 3, but using your logic you'd say they purposefully side-stepped everything they originally set out to do.
