I'm curious Morbid, have you considered before that it was just clones from past Smash games which may have, as you perceive, altered the playing grounds for Lucina?
I disagree on many of the points you bring up about Pit's favor, but one thing I do agree on is that there is of course the possibility that Lucina is not the only clone, and that she may have been swayed into creation based on another characters split. You argue Dark Pit and Dr Mario (though I've not read into why Dr Mario), and I'm curious why you would not consider the possibility that characters like Lucas and Ness were going to be alternates, and that they instead were the ones who were divided, which gave rise to your infamous
However.
