You can make a sensible argument that someone is in the lead at time-over.
You can't make a sensible argument that Bowser wins in a situation that the game only allows him to lose or tie.
Bowser is landing a kill move on the argument, just like Ganondorf and Dedede. There's no reason one move should be treated differently from the others. Bowser can't even force you off the edge unless he has a 40% or more lead, and even then he only has 10% more control than you. He needs an 80%+ lead to gain significant control.
Besides, to quote a previous post of yours, the game tests your ability to KO people off ledges, not build %. Bowser is almost always behind in % in matches, but that doesn't mean he's losing. Hell, when Bowser gets to high %, it just means he's on a new level of terrifying if he gets the right read. I don't feel behind at all when at high % unless my opponent is at a very low %. Certainly, if I am at 100% and my opponent is at 99%, I don't feel behind in the slighest - I feel ahead, especially if I am playing a light opponent like Fox or Sheik. I don't think the % lead argument holds as being logical for this game. We do it out of convenience, and because there is no good alternative.
I do, it's rough since I just moved into my new place and I'm on 4G, but I may have to play on that or wait until Friday where I should have internet. But it'll be complete.
I don't think that's as comparable. Sudden Death not being allowed should be pretty obvious (it effectively changes the outcome of the match to a mini-game with how random it is). Bowsercide always causes Bowser to lose or get Sudden Death in this game, he does not get a win. It's bugged, yes, but it's consistent in the game that Bowser does not get the win.
Also in the one instance where a suicide move always results in a win = Ganondorf, the game is clearly designed with this in mind. Trying to do Ganondorf's sideB near a ledge can result in his SD, whereas most other similar moves do not throw the user off the ledge.
It's "lose or sudden death", so the game is inconsistent. In the last patch, it always won. It wouldn't make sense to count the "sudden death" result as a loss, would it? Should I force players to play that situation out? What should we do if the game goes to sudden death?
The game was also clearly designed so that Bowser wins off the Klaw SD, but then the last patch glitched the move. I suspect that the move will be fixed in 8 days, anyway.
Bowser's move isn't the only one that can grab you neutrally on the stage and then carry you off. Dedede and Kirby can do this as well.
