What's the deal with lore warden?

[Ikorus]

This may not even be the correct board for this, but looking up some other stuff prompted me to take a look at this fighter archetype, which there are two different versions of.

Looking up WHY there are two versions, it turns out the objectively worse one is more recent, and is explicitly a nerf meant to replace the old one entirely in pfs. I dont necessarily agree with this; the idea of trading your 2nd level feat and bravery to not need 13 int for a forced feat you dont get to ACTUALLY benefit from until 4 levels later on an archetype specifically meant to make not dumping int into the toilet offer something akin to actual value seems like really questionable design. But that's not what this is about.

The thing is, archives of nethys marks BOTH versions with its play-legal symplbol. Not even the red ring of "well, yes BUT". I'm wondering what that's about. I thought the old version was meant to be explicitly illegal now, and I havent found anything stating the contrary. Is it a chained/unchained situation like the barbarian where you pick pick based on your build (although why would you ever use the new version of lore warden)? Is AoN just WRONG?

I believe you can play a lore warden if you own the old source, you just have to use the new rules. Which were published online somewhere. It was a compromise so that people who owned the old source and had lore wardens weren’t required to own the new book. So that probably resulted in some confusion with the listing at archives of Nethys.

There has been enough abuses with the older version of the archetype that it needed to be nerfed for Organized Play use. In home games, as players and GMs see fit.

The controversy and name calling about that was enough alone of a reason why it was long overdue, and it's not naming the other reasons.
