What are your negative predictions for Smash 6?
I'll list mine as examples.
Marth will stay as a mid to low tier character. They will copy paste his moveset and hitboxes from Ult and then make the game even more obnoxious for him so he cannot land any tippers and secure stocks. He was already uncared for in Ult I doubt it would change, especially if the next game is an Ult Deluxe.
We will not get any updates to the defensive mechanics in the game (so no power shielding), so projectile characters will still be annoying as hell online. Also parries will continue to be rather unrewarding. If I parry Cloud's Bair I should be able to punish that move. He shouldn't get to keep spamming such a fast disjoint on me. Mashing is just too strong and not cool
Online will not get fixed.
Phoenix Wright will never show up :(
