Final Smashes are too powerful and impact the game too much, it'd only bother people if they were adapted to a less random standard that relied on building meter. Even if you nerf them, their change on the formula is too huge... which makes another problem. It becomes gimmicky. Little Mac only has this because he really REALLY needs it.
Items themselves can't even be considered unless they lose their RNG spawning algorithm that's just... so abysmal. Even then, 64 had the most balanced and unimpeding item set in the series, if that's what you wanted to hear from me. I think Smash 4 made most items way too powerful and complicated, they're better when basic because they require more thought, input, and perhaps even skill from the player.
EDIT: Also I have no idea how you got "too shallow to understand" from "not interested, no thanks".
