I'd like to see ammo's +20 potency apply to Lead Shot's DoT,
Rend Mind/Dismantle/ Hotshot up to 10%
And reload on 45sec cooldown, to line up better w/ wildfire.

It would have been cool for Ammo to have a variety of effects depending on the skill, but... too late for them to do it now, i suppose.

(a little work on animations, and the ammo box model changing w/ the gun would be nice too..)
