I can agree with some of this, I will firmly disagree he is better here than in Brawl, different meta-games, different tools, I don't believe Lucario is that good here when a lot of his moveset is answerable with the same things your trying to stop, camping him back.
Lucario's goal is to always be on your hide and he has the mobility for that. His Down B is one of his means to avoid camping. He also has a great wavedash, dash-dance and moonwalk that he can use to get around. If you get camped too much, you are doing something wrong.
He shoots Aura sphere for a set-up, just run away from him and move somewhere where he can't follow it up. Only on stages like FD is he going to be better with catching characters in a way where he can attempt to force it with a throw into it. I recognize he can use it to edge guard, If the mechanics of melee work here with the ledge and how some characters recover.
It's also a stage control. I've used it against Bowser on Battlefield very often to keep him above me and also to mess up his super armour timing. I've also used it to force people to shield, jump, roll, thus allowing me to get an attack in. Most of the time, you won't aim to hit with the move but to force someone to move and if he's camping, to stop camping you. Lucario is heavy on mindgames. You got to be very creative.
You need an even harder read than what you needed in Brawl to catch people with a SuperSphere. Making it even slower is just going to make it more limited in usage. Even if there are set-ups into it, nothing is really stopping character from playing keep away and safe until it goes away. It's stage control momentarily, and then you'll lose it until you have to build it up slowly again in which I can only see 2 charges max per stock, maybe 3, 4 if your lucky.
you underestimate slow projectiles. The appeal of them is that they are hard to dodge. You can't spotdodge it and most rolls can't do a thing about it. It's difficult to powershield and also, it allows you to work around it. While I find it more useful against poeple offstage because their options are limited, you can find use for it on every stage. It helps you approach them while they are playing keep-away by limiting their movement options if anything.
Furthermore, you will rarely need more than 1-2 charges to seal the deal, and if you play your cards right, you can easily gain one in a single combo and possibly up to two if you did something amazing. Two to three solid comboes should give your full charge. You also must never rely too much on charges. If you think you can kill without your charge without risk, do it. If the situation calls for using a charge, don't worry about losing it, just do it. It'll disappear if you die anyways. There's much thought that goes into when and how to properly use a charge, but you need to get good enough to play with the assumption you don't have a charge at all times
I can sort of understand the point of might not working as well in Melee, though being fair 0-deaths aren't that common if not rare even more so after watching APEX 2012, I was there. From an edgeguard sure, but I do think it is possible to scale it in a way it doesn't bone him over if that is a problem.
Yes, but they are still more common than in Brawl, but that's a battle system difference. But I'll be honest with you. I personally think that Lucario's aura system in Brawl is a pointless gimmick. As for why he was changed, I wasn't part of the team when that direction started so you're going to have to ask shanus about that. But I can see why this aura system was dropped. The Brawl version of aura had the issue of making Damage and KB iconsistent for Lucario, and while it boosted his power, his combo ability suffered in the end. So as it increased, Lucario had an easier time killing, he did less damage per second. In a sense, against a low percent foes, his aura system became a liability. For a game like Project M, this weakness is more crippling. tIt's not that you can't combo in Brawl, but it was a bit more forgiving.
Our new system makes Lucario into a much more agressive fighter, but also makes his bread and butter comboes more consistent.
I see him being changed, I don't see him holding his own very well in this kind of environment.
I held out pretty well against the legion and I consider them better players than I. I've improved since then and I'm pretty sure Lucario is good enough to fight at high levels. He has other tools to make him good, trust me. At least give it a try (several because he's hard to to master)

. Keep in mind, this is an entierly different game. Brawl aura hurts Lucario a LOT in a Melee environment.
