Useful is subjective. Your post is useless in my eyes. Your mere existence is useless in my eyes as well, and in the eyes of many others I'm sure. Shut up.
I asked why the topic creator would want wavedashing and gave my reasons for asking aside from curiosity. I got a (somewhat defensive) answer. While I don't see the appeal of wavedashing, I'm not the one using it so I was going to leave it at that and probably grab the code that PW made. Someone already posted it, so I decided I wouldn't bother. Then I saw your post. Your white knight attitude is irritating. Your post was a poor attempt to act like the "bigger man," and quite honestly if you had wanted to do that you should've just stayed the heck out of it.
Oh and by the way, Unknownlight, Brawl+ isn't made so that everyone can play Brawl the way they want. That's what the individual codes are for, yes, but Brawl+ is a massive project consisting of a carefully-tested, specific set of codes that attempt to improve the game in multiple ways. Sure, you can customize Brawl+, but then it isn't an official Brawl+ codeset and can't really be counted. One could argue that Brawl+ is made so that people can play what the Smash community wants from Smash on average, but that is different than what you're saying.
I swear to God, I can't post one simple question without getting eaten alive by butt-hurt White Knights. If I was flaming the topic creator or whatever than fine, by all means have at me. Oh wait, I wasn't.
So let me reiterate. Shut up.
