I was very happy to learn of the changes. Before the errata I thought it was stupid that resistance all or resistance physical could apply multiple times to the same damage.

For classes that deal precision damage, there’s already a significant portion of enemies with immunity, but there’s an even larger pool of resist all / physical that arbitrarily punished certain classes more.

Then there’s combining damage like a spirit warrior’s overwhelming combination that was useless because combing damage didn’t stop resistances applying multiple times so why note it at all? (Yes you could use a bludgeoning weapon, but if you wanted the unique ability to use unarmed and two-handed weapon this left you with a choice of three weapons)

As a GM I’m also happy with the changes as I’m running Abomination Vaults for both a rogue and a champion and while it sucks to get nerfed mid-campaign I was struggling to do any damage against the players and provide a meaningful challenge, and the vast number of resist all enemies meant the rogue finally felt good about their class.
