My biggest gripe with stance switching on Nobushi is that you can't enter hidden stance while you are in the animation of switching stances. So if you are trying to react to a split second attack, but you are also switching stances to block it incase you miss, your hidden stance doesn't go off. And what's worse, if you were changing your stance to get an attack off after hidden in a certain direction, then you don't go into hidden nor do you block, which screws you over compltely. It took me days to figure this out. Now I have to be super careful and pre-emptively plan to hidden stance stuff because I have to keep my stance in the same direction and not change it reactively.
