PSA each reset of well if the mind can shuffle node options
Some seem fixed like the mastery nodes but for the last few days I've been resetting and confirmed that the Slayer-resistance nodes shuffle.
I've also noticed that sometimes when there's a patch they get shuffled anyway, appear to still be fine, but sometimes break completely requiring a reset to get a working Slayer-resistance.
It's worth it to shuffle until you get what you need for the content you're in. Undead Slayer resistance effectively negates the damage reduction, while warped one slayer resistance *should* help against GWO bosses.
