This thread is getting too de-railed into historical discussion. I'm aware of the mixed unit thing, however I don't think they will do this and I personally hope they do not. I'd much prefer the tactical options and considerations that come from staying with one weapon to a unit rather than complete historical accuracy. If I was being really accurate I wouldn't have put up the nodachi, nagamaki, kanabo/tetsubo, or ono/masakari at all since they were very rarely used in actual battles.

Historically accurate sengoku jidai warfare is basically going to be push-of-pikes (yari) plus guns with some naginata and yumi thrown in and that's about it. Real warfare in general is very boring, repetitive, and random. Verisimilitude and immersion is important to me in a game, hence my concern about very silly units like battlefield ninja again, but total factuality is not (and is better avoided). Another way to put it is to give options that a daimyo theoretically could have employed and *feel* real on a battlefield, like simply equipping your samurai with nagamaki even though it was actually rare, as opposed to units that have semi-magical powers like hiding in plain sight.
