Make bows only lose enchanting charge when you actually hit an something living for actual damage like every other weapon.
Make stagger shots depend on location, so a headshot or torso shot will always stagger like Destruction dual-cast always staggers.
Have limb shots slow fleeing run speed considerably.
Increase perk damage multiplier for bows. Come on with the 15x damage (plus gear to make it 30x) for daggers and only 3x for bows?
Add finisher moves for bows? Maybe they exist but at level thirty I have still yet to see one.
Remove the penalty for quick-firing arrows, or speed up the animation for equipping the bow and pulling back the string considerably.
The arrow is enchanted as it leaves the bow. I do not see a problem with this.
Stagger by location could be fun as could limb damage but I do not have a problem with the way it works right now. With respect to magic, if I remember correctly destruction does not benefit from sneak, let off a fire ball and you light up like a Christmas tree and no bonus, so there's the balancing factor.
Limb damage, could be fun.
Increased multiplier? I do not think this is necessary, mobs are falling fast enough as it is.
Finishing moves? Only if I can switch them off. How am I supposed to drop 5 mobs in rapid succession if the game keeps messing with my view of the situation, my aim and my timing?
Sorry, but once again I'm not experiencing any problems with my rate of fire.
Edit:
Targeting is a little odd at times, it's easier to hit a wolf at distance than a troll, but I can live with it.
