Can't see anything because of the fascination with night battles...
Perhaps they have some secrets they yet want to reveal!

I really hope they don’t overdo the rock, paper, scissors thing. For example, if they let sword troops have some sort of inherent advantage over yari troops, that would be incorrect with no basis in Japanese history. If they just let the troops behave as they did in reality all will be well. Units need no artificial advantages or penalties versus one another.
Perhaps the RPS is most sound when all units involved are green. Perhaps an experienced yari troop will have an advantage over a green sword troop? I always wanted CA to do something more with green vs. experienced troops rather than just a valor bonus.
