As I
outlined in this thread, I don't agree on making rules to buff specific characters and I think that, since Smash 4 actually seems to have consistency post patch, we should not award the win to Bowser.
We actually did a ton of testing on both Reddit and the thread I just linked to. The result was this: If Bowser's Flying Slam goes offstage and both players die, Bowser will either lose, or the game will go to sudden death. With the sole exception of Ganondorf's side-B, this is consistent across ALL suicide moves, including Kirby's. There is no result in which (again excepting Ganon's) the suicider ever wins. Therefore, a simple rule of "Sudden Death = Suicide Initiator Loses" covers all situations consistently without ever having to ignore the victory screen.
In Melee, you
never ignored the victory screen. Suicide rules only covered sudden death. In Brawl, it was necessary to ignore the game's victory screen because the game used Port Priority for it's decisions. In Smash 4, the game seems clearly intended to not let the suicide-initiator win, perhaps in an effort to discourage suicide kills.
Making an artificial "Bowser should always win" rule sets a bad precedent. We shouldn't ignore the win screen, ever, IMO, in Smash 4. The rule should be "Go by the win screen, and if it's sudden death, the suicide initiator
loses." This results in consistency in all situations.
That said, your story is terrible and I feel really bad for you
The TO should have required a one stock do-over to resolve the situation IMO.
Given what happened, they should at
least have refunded you your tournament entry, because you were eliminated due to a TO mistake. Simply unacceptable.
