Yes, the Lucky option is a meta mechanic - luck is not controlled by the character.I mean this is a clear meta mechanic. It has the player to make decisions that their character is not making (presumably the character doesn't knowingly decide when the luck manifests) and at least as you presented it, leads to reality editing.
I literally banned lucky feat from my 5e campaign, granted, mostly because it is absurdly good and overshadows other feats. Though I don't think e5 lucky really results any reality editing, as it is just a reroll. It doesn't actually let the character do anything they hadn't a chance to do in the first place.
Now, i sees you would not enjoy it. Do you accept that some games, like 5e with it's Lucky feat or Diviner feature, can have meta mechanics and still be valid RPGs that some enjoy?
Basically, I'm trying to determine if this is a personal preference, or if you think everyone who plays D&D with meta mechanics are doing something wrong.
