OBSERVED: Few classes are able to obtain weapon specialization other than fighter classes. Actually swashbuckler is the only exception. However, despite gaining the other benefits of specialization, swashbucklers don't also receive the extra half-attack per round. This is consistent with PnP rules and BG itself because only fighters receive APR bonuses by their class. However, this leads to some contention and confusion because there is nothing in the description of specialization on the Character Generation screen which mentions bonus APR as an exclusively fighter benefit.
EXPECTED: Add a single line to the Character Generation "Proficiencies" screen description of specialization, mastery, etc. that they only apply to fighter classes.
