It worked on Peach as well. And a few others.
It really doesn't, maybe extremely rarely. (and again, DI is a thing)
Nonviable characters don't count (and who are you even referring to there, kirby?)
And obscenely early kills that are matchup specific. And every instance has double the effect because of the roster list. But hey. Smash4's entire cast is obviously capable of this, so it's a much different issue! Oh.. Wait. Most of the instances are character specific or matchup specific?! Exactly like Yoshi's! Who'd a thunk it?
Err, they're not character or matchup specific in smash 4, it's like every move that sends you up with high base knockback. (there are a few outliers that get noticed more, like rosalina, but it's not like the blastzone's only a problem in those cases)
I don't know what game you're playing
Only person "strawmanning" is you. (Wasn't a strawman btw. Accusing people of things they aren't doing isn't a valid argument)
You compared my argument to banning yoshi's in melee, said that in that case it's not an issue (and thus shouldn't be banned), implying my argument is invalid. That's a strawman. There are numerous aspects that make the two circumstances (halberd in smash 4 and yoshi's in melee) different. You can't argue that because yoshi's isn't banned, halberd shouldn't be, it's not relevant.
Walkoffs are banned because of the gameplay that is forced to occur on them, not the result of that gameplay. It is can't be compared directly simply because of the nature of both issues. You have to stretch really, really far to make a comparison (like you are) because they are separate issues. One has early kills, and the other essentially stops the game from being played.
lolwut.
Walkoffs don't stop the game from being played, pretty sure delfino and castle siege are fine during their transitions. The whole reason they're banned is tradition from previous games, but if you analyse it, it's because of the stupid risk that approaching near the blast zone creates because both characters are at kill % really early. It's the same on Halberd, a lot of situations put you at extreme risk of losing your stock at low %s because of rage or just high base knockback and the close proximity of the top blastzone.
Again I must stress, it's not just that things kill earlier on Halberd, (fox killing earlier is fine) it's that gimmicks that wouldn't kill you on any other stage now take your stock.
When you counter-pick halberd (and delfino, but delfino is generally ok because it's temporary) you're looking to gimmick your opponent for the win, or at least have a higher chance of defeating someon better than you because of the high variance of the stage (through really early kills and hazards), it's not conducive to competitive gameplay.
No, Halberd shouldn't be banned because it has a low top blastzone. It should be banned because of it's hazards. Either way, though, it's not like it's going to be a starter.
Well I at least agree that the hazards are enough to ban it on their own (halberd really should have been banned in Brawl), the blastzone just compounds the issue and I'll argue against Halberd using any of its negative aspects because it's a stage far worse for competition than already banned stages.
