In certain sense you were changing the rules as you were changing what the meaning of the rule is. But this is besides the point. We all know we can change things, be it fluff or rule or whatever they print in the books. I don't get why you keep repeating this Oberoni stuff. That I can change the thing doesn't mean my original criticism of the thing was invalid.
Was I changing the meaning of the rules? Greek Myth setting is Theros, 1920's Steampunk is Eberron, Mythical Europe is Forgotten Realms Sword Coast. All three of those are official DnD settings. How am I changing the rules of DnD by playing in official settings?
Sure, the Post-apocalyptic stuff was a homebrew setting, but that didn't require me to rewrite a single rule anymore than it required me to rewrite rules when my group made the Continent of Neydrig, or when you made whatever setting you play in.
And your "original criticism" is that the ability doesn't fit the narrative. But it can fit the narrative. "The Narrative" isn't something that is locked in solid stone in DnD. It is a multiverse with nearly a dozen official settings, dozens of 3PP settings, and likely thousands of unofficial settings. All using the same rules. It isn't the Oberoni fallacy to say that, in a game where we constantly make up new narratives, the problem of "this ability isn't in the narrative" can be solved by changing the narrative you are defaulting to.
Oh, and I did not ban luck feat because it is meta, I banned it because it is OP and boring.
Good for you. Being OP (in your opinion) and boring (in your opinion) does not mean it must by its very nature be a meta-narrative construct that could never be worked into the narrative in the way you desire.
