Okay, Kupo, I'll elaborate on G&W, DDD, Kirby, and MK.
G&W feels heavy due to down grav. Whenever he jumps, I can feel something pulling him down. This is rather bad as this constant downward force is causing him to be even more susceptible to combos, and he could already be easily comboed in the first place. The dgrav, I felt, pushed him out of semi-floaty range and into regular range or so. He doesn't have the weight to back up this change, nor does he have the tools to be aggressive enough to facilitate this change. If he needs dgrav, put him at around 1.2 or so.
By DDD having a fast fall, I meant he had a fast regular fall, not a fast fast fall. His regular fall is kinda ridiculous, as it makes him more susceptible to combos, and makes it very hard for him to recover and edgeguard off stage, which shouldn't be the case since he was designed to edgeguard off stage and recover well with his multiple jumps and such.
Me and my friend played as Kirby and MK, and it felt like we were moving through a down flowing stream of syrup. Jumps felt awkward, as did trying to chase in the air and edgeguarding. However, while I'm sure dgrav is the issue, I'm not sure if you should lower that or simply increase upgrav to make their jumps feel tighter. I recently played melee, and characters there fell pretty fast, but they rose preety fast too, and thus the physics made sense. However, with this increase in gravity, the off stage game was lost, which I find to be awesome in brawl+. Thus, I don't really know what you should do for them. You could try decreasing dgrav a bit for them, or you could increase upgrav and see what happens.
Also, my friend dabbles in Wario, and he stated that Wario has lost his floatiness, which is a hallmark of Wario, and I'm sure many a Wario+ main would be remiss if he were no longer floaty. I can only assume it was dgrav that caused this, as my riend had the same complaint I did with G&W about Wario feeling heavy and bogged down.
Though, oddly enough, when I tried Ness, he felt AWESOME. I'm not sure why, but it just felt so right for him to be able to combo people the way he did, with dash attacks into bairs and dthrows into almost anything, Ness felt really good, and I wish for the Brawl+ BR to look into Kupo's values for Ness to see if they could refine them.
And I owe you an apology, Kupo. I did overreact a bit, because my usual characters felt so very off with your set. However, others felt great, which led me to believe tht this set is great for some characters but very bad for others, and generally you set seems to favor naturally heavy fallers and it seems to hate naturally floaty fighters, though there are exceptions(Ness).
As for your response on consistency, I think I see what you're getting at. However, the chracter division constant is based on floatiness or lack thereof, not weight. I'm sure weight is a factor, though, considering how it affects launch distance. Like I said, if we had character specific hitstun, we can mess with these values more than we can now.
No one wants it except me, leaf, and you? Well, who could make it for us? PW is on hiatus, and spunit has a borked computer, What about Almas, could he do it?
