I'm not so sure about this tbh. Like I'm aware of the rule and how tournaments decide these things, but I thought that the rule was brought in, at least for the most part, as a way of avoiding sudden death situations deciding the match, much like percentage wins work when the timer runs out and both players have equal stocks. But now that the game has made a definitive stand on who will always win in a player v player scenario and the sudden death situation is no longer a factor, I can't help but think that people will lean towards saying that while it is a shame for Bowser and it doesn't make sense, the game was made this way, these are the rules, let the game decide.Remember: we'll still get the win in tournaments.
I realise that I'm bringing this up on the Bowser boards and I may be opening myself up to reactionary posts, but in all seriousness, I think that this is a very possible outcome.
