Finesse: the reasons I put +1% Crit. Chance is that I'd also consider changing Talents. Even though I didn't post it here because I haven't thought of all the talents and their implications, I was thinking of changing [Back-stabber] to +25% (or more) Crit. chance when attacking from behind, not requiring Daggers.
For Accuracy and Block/Dodge chance %numbers, I was just trying to find an arbitrary number but yes 2% might be more balanced.
Ranged: While they do have access to [Mark] which removes Dodge chance, it wouldn't remove block chance which is why I put it there.
Aero: Can't really find something to make it better maybe 1% status effect as well since they do have Stun and Blind?
