cultural proficiencies: a modest proposal

The idea here is that "martial weapons" refers to the type of weapons used by the warriors of a given culture rather than just "weapons that are good."

Everyone can add their base attack bonus/proficiency bonus to attacks with a crossbow (2H 1d8, loading), dagger (2d4 in a grapple, 1d4 otherwise) or one-handed tool (1d6) such as a cleaver, hammer, hand axe, etc.

Fighters are proficient with the weapons of their culture. Other martial classes may have specific weapon groups associated with them. You can learn a group (or a specific exotic weapon) as a feat if you have a teacher.

• Northern men: battle-axe (1H 1d8 or 2H 1d10), saex (1H 1d8) and thrown hand-axe.
• Paladins and Eastern men: mace (1H 1d8), thrusting spear and arming sword (both 1H 1d8 or 2H 1d10).
• Southern men: thrown or thrusting spear (1H/thrown 1d8 or 2H 1d10) and gladius (1H 1d8).
• Elves, Rangers and Western men: self bow (2H 1d8), thrusting sword (1H, 1d8 finesse).
• Dwarves: battle-axe and war-hammer (both 1H 1d8 or 2H 1d10). 
• Barbarians and Goblins: mace, saber (both 1H 1d8) and composite bow (2H 1d8 ranged).

Attacks with these weapons are not usually penalized if you are not proficient. Attacks with exotic weapons are at a -3 penalty for the non-proficient.
