Honestly I'm not sure where mch's dps stands against the other ranged but I think the fact the it feels more like a pure dps then support is because it is. Obviously they want to keep ranged dps with some support in their role actions but it feels like overall they want there to be less focus on support and they decided to make mch range's equivalent to blm and sam. Mch will have greater mobility then blm and being ranged means it has less chance of being hit by melee AOEs. Where it stand overall idk but from my what little play I have done with it it feels like it hits hard.
