• That’s what all the new content for the next 10 years will be based on. The old core rules are still there, but everything new will be based on the new books. That’s a lot like saying not everyone will be playing a sequel, which is true, but the community will shift over to it in time. The new PHB is there fasting selling book ever, so that gonna be pretty fast. Especially once more new content comes out and is incompatible with the old rules

• I don’t care about your moral argument here, even if I agree with your stance, that’s not what I’m here for. If your stance is that strong, I would recommend leaving DnD behind and moving to Pathfinder or another alternative, otherwise every new discussion will be covering materials you refuse to consume (for completely understandable reasons). Your players are going to want to something from the new rules at some point, and you will have to be the bad guy there. Even by being here and discussing the game, you are consuming the new rules and driving engagement with them.

• Ok? The new DMG is out. This rule is not in there.

• I find that unlikely. Everyone has the free rules, and a lot of the DMG content is in the free rules. You’d have to find some way of doing encounter math, which the free rules has, but I’m sure a lot of paper players have the DMG, even if just for that.

• They updated falling in the new PHB, including adding a DC15 (Athletics) or (Acrobatics) to change a fall into a dive when falling into a liquid to take half damage. Your telling me they couldn’t have added a very similar rule, or even added onto that section to include falling onto other creatures if they wanted to?

Your right, all of this doesn’t matter. This rule takes the fun out of dropping something big onto someone as size doesn’t matter for fall damage. Players might as well drop themselves onto the BBEG, same effect. You killed my fun, so I’m not participating with you.

If a simple nope ticks you off that much, I’m not sure who you could play with. Do you remember every rule interaction off the top of your head? Never get anything wrong? I play with players and DMs of vastly varying skill and experience levels and everyone gets something wrong every session. If someone corrects them and they snap about respect, whether DM or player, that’s a bridge too far and we would all be having words afterwards, if it didn’t derail the session right then and there.

Respect is something which is earned and goes both ways. Saying your rule is law like your Aku doesn’t seem very respectful.

I’d agree in general, but they copied the other rule about falling into liquid off the same page from Tasha’s without modifications and not the rules for falling onto other creatures.

They specifically chose not to have those rules when it would have been no effort to add them.

And they did update falling, by adding the section about falling into liquid, and describing it as a hazard.

That signals to me they very clearly did not want those rules as the new baseline for the game.
