I think they said you can redo stats as you please with this patch so it's not permanent, not 100% certain though. Also you are pretty much stuck doing one of two things, STR VIT or STR MND both provide minor boosts that are not game breaking or really worth arguing over which is superior. Only thing that really matters to help decide what to do is to see how much, if any, MND you get from PLD AF. Fairly certain all secondary AA stat boosts have a hard cap similar to DEX for archer so after awhile going past that is only giving minor healing increases.

Really hoping PLD has some percentage based damage reduction traits that help reduce damage, going to be really sad if they just throw on some extra 50 defense or something
