Melee combat has Trip, Improved Trip, Sunder, Improved Sunder, and Stunning Blow. Well, there is Stunning Fist, but that's only for Monks.
I think we need some granted combat feats for ranged weapons, in the same way that everyone gets access to Trip and Sunder. Say, for example:
Impale Arm: You aim your shot/throw at the enemy's arm, slowing their arm movements and giving them -20% attack speed for 30 seconds. You take a -4 penalty to your attack roll when using this ability.
There would also be others, but that's just one example. My thought is that while melee combat feats are focused around making it easier to deal more damage, ranged combat feats would focus on impairing the target.
The only problem I see with adding more ranged combat feats is that the ranged combat style is VERY feat-heavy, and if there were "Improved" versions of these combat feats, it would be difficult for anyone who isn't a fighter or ranger to take these feats. I would suggest improving the attack speed of ranged weapons and getting rid of feats that increase attack speed before implimenting any "Improved" ranged tactical feats.
