Will say the issue with RDM being able to have a potent cure, raise, SMN having a raise and not so potent cure and BLM getting nothing, he's missing the point of how useful those tools are to have outside the support role.

A RDM able to cure strong can keep a tank alive in a dire moment, can revive healers that both died, SMN can do the raising part, but BLM gets nothing in that respect. RDM can even have instant access to "Swift casting" any cure or raise. Only adjustments I would suggest in this respect is either remove Cure/Raise from being able to dualcast, increase the mp cost of the cure or lower the potency and maybe have it where SMN/RDM can only raise targets that don't have weakness and when they raise the target has double weakness.
