3 AP crossbow does seem like too much for how little the damage seems to be improved vs. a bow of the same level. I think it's a good direction, but, may need more tweaks.
3AP crossbow is a step back to the old AP balance.
It's not strictly a bad thing, but it defeats the point of having less action points to work with(less math involved, actions scaled by significance) in the first place.
1AP per hand was a good system that really didn't need changing, but somewhere alongside the shield ability being added(which I'm proud of to have inspired) they decided that while they're fixing what wasn't working too geat, they might as well screw up what was.
