If you also want to talk ease of getting the "relic" weapons look at FF3 (put this in because CT will be out soon) all you had to do was really do. A little quest and fight a boss which by that point is easy to get the ultimate weapon then it's as simple as max out a job to 99 and free max weapon for that job.

So by Yoshi saying he's going back to the roots, if you look at almost every FF game the ultimate weapons are pretty easy to get.
