Dysfunctional Rules VIII: When General Trumps Specific

[ShiningStarling]

Benefit
You make attack rolls with the weapon normally.

Normal
A character who uses a weapon with which he or she is not proficient takes a -4 penalty on attack rolls.

Not sure if it has been done, but the Weapon Proficiency feats does nothing. The "Benefit" does not grant "proficiency", it simply states that you make attack rolls normally. It then tells you that normally you take a -4 penalty.
