i actually wouldnt doubt it if they change rolling. Thats the only thing that is a uniform complaint across the board no matter who youre playing. Even characters that are bad at it (dk) can still do it effectively and safely if you know what youre doing.
If theres ANY character balances outside the rolling, i suspect it would be little mac. Honestly, remove his super armor on his smashes and he'd be fine. Its not his speed/strength alone that makes him insane, its that you have to beat his speed or he kills you anyway even if you did hit him thanks to so many super armor on FAST attacks (everyone else is slow attacks, even DK's punch has a moment where the armor doesnt exist)
