The mechanical importance of the pantheon. My campaign is based off of Hyrule and the three goddesses. The party's Champion isn't worshipping any god, my finacee's Oracle is a priestess of all three, collectively, and I don't have the time of day for the restrictions imposed by having domains limited to certain gods.

Divine players can choose whichever domains they want, as far as I care.

I'm also not a purist of tracking hands, or even bulk. Having to spend actions to grab things out of your backpack is a straight up feel bad for most players.

But I don't know that I consider either of these "dumb", though. They're just not for every table.

What I do find dumb is the attitude that seems to permeate r/ that the published rules are somehow something more than recommendations from the design team.

The rules are just what the designers believed worked best with the system's core features, given their restraints (time, pages, money). They're not some unerring holynl text, and one table trying some perhaps unbalanced homebrew doesn't affect anyone not sitting at it.
