Extend Classes into full Jobs?

[Bishop81]

You can't see because you're not looking hard enough. There is something that is a waste of time, that's making classes that play exactly the same as each other.

...

Let's SE determine what is and isn't a waste of their time.

The game isn't only about "functionality". A NIN isn't a ROG and a ROG isn't a NIN.

If they do extend classes into full Jobs, what makes you think they won't add Job specific abilities to "differentiate" the 2 jobs?

Also, again, so what if they are similar mechanics-wise?

If you really want to "not waste time", might as well just have "fighter", "thief", "priest" and "wizard", then call it a day.
