I've always imagined CHM as a healer with no cast time to use potions for healing but mixing or amalgamating them does require a cast time. It would be a high mobility healer and a handbag as a weapon true to its FFT roots. It might get more people to heal if there is a job that has a satchel/purse as a glam weapon. I know I would love it since I can finally complete my Dawn pokemon glam. Though I'm much more interested in the story CHM can tell from the Garlean side, being void of traditional magic like the rest of Eorzea, they can tell of the hardships of finding cures or the unfortunate realities of progress in medicine. It would very much parallel our reality and contrast to how healers in Eorzea can just heal in the CNJ guild, almost any sickness, but CHM is limited in resource and technology.
