Meh, restricting weapons to different classes makes sense in games, but from an RP standpoint, whats to stop a disarmed Mercenary from picking up a spear? and in most armies, a spearman is often armed with a shield and some sort of short sword as well. Sure they would be considerably less proficient at it- like an E or F on this scale, but what would stop anyone in this RP from picking up a fallen weapon?

I'd just thought it'd make sense not to give the frail bodied dragon-kid a battleaxe, so I was going for a light-magic tome. I mean, a mage picks up magic because he's either intelligent, or lacks physical strength. Just as well, a fighter picks up an axe because he's good at smacking stuff. But sure, I can go for a sword or something like that.
