I've come the to the realization that no matter how many skills you are given people still won't be able to dodge mechanics or fully execute DPS rotations properly. While I can't go the "Illusion of Choice" route I can go with "Over Saturation". This means skills will still be diluted down to the best choices anyways wasting the developer's time and energy.

The only thing that changes is what skills players die with on their hotbars because they will still wipe on the same things. Final Fantasy is based on the diversity of jobs not the over complexity of them.

Instead of focusing on a cross class system they should focus on adding more jobs to give players a broader spectrum of play styles.
