The only issue with this model is that Dex no longer scales damage...this is difficult to address, unless maybe Dex can do something like scale Crit Dmg or Crit Chance for ANY weapon type. This makes sense especially if we take out Crit Chance from Wits, which I never liked to begin with. I always saw wits as "perception" for hidden out of combat things, so if wits only modifies "perception" and initiative, then that also gets rid of the problem with wits being "too strong".
