Yeah! That is some change that I like!
Exploding bolts would be cool too. And like I wrote (like before) about potential for special damage should be fully utilized. I'm mainly talking about special shots targetting limbs (I know there are already such skills, but weapon differentiation would be great - like greater chance for such skill to apply or even a tiny chance to condition appear on it's own, which could give crossbow different flavor from guns).
These are of course only suggestions, but I'm glad that work is still being done as I'm afraid that the forum is slowly dying.
