My point of view comes from using ACN attacks in RP, which includes the dark-aspected poisoning attacks. While fire/ice/lightning may have the same effect on a person whether it was started naturally or by a spell, there are so many kinds of non-magical poison that I can't see ACN's attacks acting as one (or three) specifically when we don't know much about their effects beyond "makes HP go down" (and Miasma's extra affects via the Malady status, which aren't very specific to a single poison either).
I've also always treated "magic resistance" as something that would come to an experianced magic user, not an incapable one. A skilled THM has a better chance of being able to use their own aether to prevent damage. We kind of see this in-game by seeing that caster armor has a higher Magic Defense stat than even tank armor.
