You could add positionals and even charged attacks onto physical ranged. I think that the automatic treatment of physical ranged as obligate inferiors to magical ranged is really strange, especially when jobs like PCT are both mobile and have similar utility while providing much more damage. Perhaps introducing in sniper style 'casts' on a few actions could also be a way of demonstrating equivalence. It doesn't have to be every action, of course, because even magical ranged aren't designed that way nowadays.

That being said, given how controversial some of these things become, physical ranged players should probably have a discussion as a role to see what they want to do in terms of positionals and casts.
