Second part - I'm not trying to make battles faster. Right now crit does everything attack does and more. It makes up your raw damage in the same way as attack does (or at least the way it worked in the version we got to test, but maybe not in that screenshot) with the added bonus of sometimes giving more through a crit and/or a non-glancing hit. So with the sole exception of pumping up Distracting Blows, there's no reason to get more attack than crit, which makes it a no-brainer of keep them almost even with crit a little higher or you're unambiguously gimping yourself. Unless you're Joanne, in which case it seems the stats still do the exact same thing.
The point of the defense piercing ability isn't to be the best attack in every situation. If it is, just nerf it till it's only good against high defense targets. As an alternative to wittling down their defense with Backstab and the likes.
