First, for weapon katas, am I correct that the weapon katas use the weapons size modifier to the critical result, or are they equal to the size of the characters unarmed martial attacks?
Second, looking at the grapple critical table compared to the strikes and sweeps tables, it looks to me like there would be no game balance reason not to make grapples another base martial arts style and drop the dragon style entirely. Am I correct to assume that grappling being a style is a flavor decision or legacy artifact from Rolemaster?
