No comments on the mechanical side of things, but there's one terminology issue I want to point out - daisho means "long-short" and refers to the pairing of swords that members of the samurai class in feudal Japan were allowed to carry.

Thus, a single sword is never a daisho, not to mention bows and other types of weapons.

Of course, Rokugan is not Japan, but it's still something of a misnomer.

Random fact: In modern Japan, the same two kanji ("dai" and "sho") are used in toilets. They're in fact the two flushing options.
