1% dodge per FIN would require a big revamp to the other sources of Dodge, because right now I am at like 50% dodge even without a hypothetical bonus to dodge from FIN. Half a point is fine, a Max-Fin build would still get a good +15% dodge.

But 1% Armor per STR/INT would also be fine, that's +30% Maxed.

I also agree with +2% each armor per CON point.
