If I was in charge, which obviously I'm not, I would have deleted SMN as it stands now, made it so SCH begins in Limsa at level 1 and re-released SMN as a "new" job in 5.0, giving everyone who currently has level 70 ACN a free jump potion to get back to 70 on the new SMN and reworked the class entirely (and made Dancer the healer while I was at it, giving us all 3 roles at expansion launch).

They've lamented over and over again that they hate the class system especially as it relates to ACN, but are unwilling to prove that they're willing to do something about it.
