The only thing I'll add, Shinobi Killfist, is that melee hardening doesn't make the weapon designed to be used in melee. It only makes it capable of taking a beating without breaking. The improvement is meant for firearms, but it even calls out that using the gun in Gun Kata it is still an improvised melee weapon.
I'm a seasoned archer myself, and I've swung around a fair share of long sticks (albeit not in the same sort of environment as the archery). And while I never would have tried to hit someone with one of my bows (because they aren't melee hardened), even if I wasn't worried about breaking it I can tell you it would be awkward and not nearly as accurate as a straight-up staff.
In action sequences like in Arrow, Oliver uses his bow to hit people fairly infrequently. Usually as part of some other maneuver, or "surprise" I still have this stick I can hit you with. There are plenty of times where he doesn't even bother using the bow and just punches with the hand holding the bow instead too.
Also, we forgot about reach, so those wageslave would only have at most 4 dice to defend (-2 from reach).
