That's pretty good. I also noticed that Knights with 'new' evasion (Saffron, bloomed JB Robinia, etc) have a set amount that never drops off compared to Knights with the 'old' version (Cypress, evolved JB Robinia, etc). So while Cypress starts with 90% evasion thanks to having 80/50 evasion along with +10% evasion for the squad she'll eventually drop to 60% while Saffron will always have 70% evasion.
With the right FMs and/or squad mates it's now possible for a Knight to always have 90% evasion, which no doubt does wonders for Kerria and anyone else with the new evasion/intercept/provoke combo.
