I can't agree more, Glamour restrictions should be gone.

The main reason Square places these limits is to avoid confusing players. So, considering this, I recommend:

* Keep the exclusive class/job restrictions. This means a gear made only for BLM can only be glamoured by BLM. This respects Square desire to avoid confusing players.

* Remove any restrictions to glamour gear from other Disciples or role. Allow BLM to glamour Disciples of War gear, or gear made for PLD WAR DRK, for example.
