I'm not following you here. Why fix it for people who won't be using it nearly as much as dedicated ranged-types? I actually sort of dig the idea of resolving it with a feat-fix, it would demonstrate that while many people can use these martial and simple weapons, only a select few can put them to effective use, as opposed to just using them as a standby.
Not intentionally thumbing my nose at you, I'm just curious as to the logic behind your desire.
