Reposting some Google Docs from the other site which compiled spoilers about the remaster from PaizoCon, so we can discuss them here. I am not the author and take no credit for any of these.
At my table we added the Divine Lance change (ie, it can actually do damage to things,) as well as ignoring the Open trait, giving Rogues access to martial weapons and Wizards access to simple weapons. Other stuff we'll probably wait for the books to come out.
We kinda ignore Alignment damage as a whole, allowing Divine Lance to damage to anything. I'm not a fan of Alignment as a whole so it was ripped out as soon as possible from my games.
