I completely disagree with you, if I’m going to be honest. It wasn’t a retcon, it was shattering people’s ‘I’m better than you’ headcanons. I’m not a fan of ‘holier than thou’ when it comes to light, or ‘only those worshipping a higher power’ can do it. That’s bland and overdone. This system is far, far better, it being willpower. “The light burns the wicked” is a completely tired trope.
Granted, I know for a fact we’re going to completely disagree on this subject, but thank gods for the way the lore is now in that case, at least. No more attitudes of worthless ‘perfection’ nonsense.
To me? They made their world so much better by clarifying.
