Regarding critical damage with the revamp

Edit: Actually, I think base mastery is tied to the weapon itself, I guess that makes more sense.
Min damage is 20% of the max damage with 1H swords, axes, and maces, and knuckles and daggers on my slinger.

[COLOR="orange"]Maybe the minimum Crit damage is the same way? Do the new Critical skills affect you only when you have the proper weapon equipped or at all times?
EDIT:Also, what if max crit damage is determined by level?[/COLOR]
