If you try to branch a healer from GLD, you have to keep in mind this healer will have things like enmity generating melee combos with no way to separate that out. You really might as well just make a new class/job entirely, it would be easier than trying to cancel all the tanking abilities.
This is blatantly false.

SMN maintains all ACN spells. SCH maintains one ACN spell, plus a few that share the same name but have different spell IDs. You can verify this yourself on the official job guides or Garland Tools. It might also be visible in game, but I'm away from my computer right now and can't check it.

While I agree that a single class branching into multiple jobs is probably a poor idea, it's not because the split jobs would necessarily have all of the base class's abilities.
