I have a Rokuma character that is a rogue. Which had me have an idea....
I was thinking, if elves are proficient at using bows and swords regardless of class, and dwarves can use the dwarven waraxe. How about Rokuma and Kara-Turan characters gaining a custom feat for using katana, shuriken, and kama regardless of class. The idea is the same. Even though a dwarven waraxe is an exotic weapon, it is not exotic to a dwarf. Katana, shuriken, and kama are common weapons to characters of Rokushima Taiyoo or Kara-Tur, so spending a feat to gain proficiency with them is a steep price for what should be a given. What are you guy's thoughts?
I think the reasoning is fair, and its not like the weapon proficiencies gained would unbalance anything I think. Either way, if i have to use the feat I will, cause I want to be true to my concept.
