Why can't we have jobs with this level of depth and customization in FFXIV?

Because this is XIV, not XI. Sorry.

This is X not Y is a terrible reason for not adding in interesting mechanics/depth to the game.
Seriously people who reply like this are stupid.

There is a huge outcry by lots of people for more depth in all areas of the game, from gear, to jobs, to the open world, to monster AI. BUT NOPE THIS IS XIV SO WE CAN'T HAVE THAT NOT AT ALL XIV DOESN'T ACCOMMODATE TO CHANGE OR CHOICES FOR THE PLAYER.
