Look you are making a standard attack with a flat percentile chance of landing it, and as you level up you find it easier to land normal attacks, by spending exp on stat advances, and there are more bonuses to landing attacks than there are to avoiding them.
When you make a special attack, like a called shot, you should compare DOS just as you do when making a full auto attack,
As it stand you are all saying you should get super special hits with basic attacks, because spending exp to avoid them easier is some how not as valid as the exp spent on making them easier, which makes zero sense.
Basic attacks should not ever be super special because nine times out of ten, there are always more bad guys than the good ones.
