It will just be ignored. Hell idk if you guys play it or know anyone who does but chances are they have been ignoring TSR et al for multiple editions. TSR rule changes are just marketing for $40 hardcover reference books. To me and all the D&D players I know, those books are worth a quick pdf download and a scroll to enjoy some art, and then they are trash or perhaps trivia. OGAD&D4LYFE

We do it this way too but if we're being honest it all comes from the framework of og AD&D and we still use those tables and references
