i don‘t see a problem using a gun+dagger combination, since we already have 2 jobs using magic staffs, 2 jobs using books etc...
i think a gun would be awesome. imagine throwing a vial up and shooting it down so it rains healing droplets from above on your team, or something that does dmg to enemies. would be neat if you ask me!
and we would leave the trope that healers have to be flashy and gracefully.
