When attacking with ranged weapons while moving, the attack roll always shows only my lowest attack bonus. For example: While fighting a skeleton kiting him at point blank range, I have a 28 bonus to hit. If I stand still, I have a 38/33/28 to hit. I have shot on the run and point blank shot. From table top rules, I should always have a 38 attack role (albeit only a single attack). I am using a Heavy Repeating Crossbow, as well.
