HARBAHGUBFAOIDFF? HGRSEJERHJR!!! HHHHHHHHHHHHHHHHHHH

I thought of this at first too, but that would be:

• A buff to daggers, guns, and (some)bows where they only need two stats for damage(skill and luck)
  
• Confusing for acid attack, where would it go
  
• Probably require a change to base skill slots
  

Guile has been around for so long and is tied to more than just crit damage that I think its better to just remove crit damage from it and find a better mechanic for guile.

That's a completely strong point. We can't really have GUI safely removed with that in mind.
I was going to say I still think GUI should give crit damage in this case, though- it's too thematic to push over, but honestly having DEF/RES have the penalty from GUI-users reducing their tankiness would make up for CEL's evasion procs being too static. It'd give an advantage to both sides of the defensive spectrum. It also means you can still build melee crit without GUI, just that you'd be more effective against dodgies than tanks. So all in all, I like it.
