Just like the title says, I think it's about time that ranged characters (bow users, but something similar can be worked out for others, I am sure) get something like Power Attack, but in turn impacts bow use.
I am thinking a 1:1 ratio, like PA, where it would be -1 to hit for each +1 damage, but impacting ranged weapons. This in turn would allow for better damage potential, as archers presently dont have any real means to boost their damage outside of merely boosting the strength stat.
Just my 2 copper.
