I have to agree with Dub. This isn't really about being 'fair' or anything. Everyone should get to play the character they want to whether it's a warrior that's really good with a sword, an archer that's really good with a bow, a wizard that can quickly draw powerful runes, or any combination of them, as well as any other combat styles. We should focus on what people CAN do rather than what they can't when compared to others. 

As Dub said, this is different than an MMO or any other type of game. Specifically, it's NOT a game and our characters shouldn't be limited to rules about what they have to do in certain combat styles. Each character will fight in whatever way they trained. Characters aren't restricted to classes such as warrior and archer. They are simply adventurers with whatever skills they have gained over the years. 

This is Roleplay, not a competitive game.
