Exclusive Hero for GMS?

Bowguns aren't too much of a stretch to imagine since Windraiders have had them for years, but how many other ways are there to use a bow and arrow? That's the textbook definition of archery, using a slingshot or blowgun or holding arrows between your fingers and slashing people with them aren't forms of archery.

How about a job that can use both Bows and XBows + have Merc arrows? That may be sweet.
