Dude, the habit has already been made, and I'm trying to fix it. I've admitted to that multiple times in this forum, once even in this thread.
It works as AA for me if you know when its usable. Which, actually, because you said what you said, I realized that, one, I've been unclear what I meant by the chair being an AntiAir, and B, I'm arguing the wrong point about the chair. I've already said this before, the chair should be strictly used to stuff other moves, and SPARINGLY. It shouldn't be spammed till kingdom come, and you will get punished if you do. Also, as I said earlier, the chair is unblockable in the air. What does this mean. If the opponent has used up all jumps getting to youhe's a sitting duck as he lands. Thats when the chair is most effective. What is the opponent going to do? Attack? Clash frames. Block? Unblockable. Air dash? Chair is faster. You see where I'm getting my reasoning? Thats why I've been primarily using it for, but if i know the opponent is going to attack, I'll beat it with the chair. You see? I guess its not(edit:holy shit, I can't believe I forgot to write not) exactly a 100% reliable antiair, but the damage output is nice, and most of the baiting options that people have on the ground don't work in the air, like side dodge, jumping away, bara canceling, etc.
Also, 5B? I know you were just trying to make a point, but that has an even worse startup than 5C.
And just a word of advice when arguing. Back up what you say with evidence, and say it calmly. If you said what you said just now a post ago, I wouldn't have branded you as just "Getting all angry because I disagree with you" and I would've had to seriously rethink my tactic that I was defending. Sure, in the end, we both still don't 100%agree, but I understand where you're coming from now, and I hope you understand where I'm coming from with this post.
