It becomes more useful in PSX patches that make W-EV automatic instead of wasting a reaction slot on them. Otherwise, it's not that great.

QuoteBlind only works when you could evade anyway. You can't evade from the side or back unless you have a shield, mantle, or are using the Parry reaction. Also doesn't work if the attack ignores evade anyway. Pretty pointless in this game due to that.
