still being a Semi Clone. Don't get me wrong, I love playing Ganondorf the way he currently is, but I really want him to get a moveset more faithful to the Zelda series. Also I hate how ugly he looks in Smash 4 (especially the Wii U version).
being too similar to
. I know that he was made at the last moment alongside
and
but at least the latters, especially Dr. Mario, have several different properties making their moveset feel a bit more different. Dark Pit only has a few moves with different properties, other than those, he's a carbon copy of Pit (Well he technically has always been one but they still could've done more to make him feel more différent).
Wobbling. I often watch competitive Melee, and I think Wobbling is such a cheap way to win matches, and several Ice Climbers mains keep abusing it.
Like many other people, Random Tripping in Brawl.
I love Smash 4, but Wii U version has the Worst modes in the series. Melee and Brawl had amazing modes like the Subspace Emissary and the Adventure mode, or Break the target. Smash for 3ds has Smash Run, which is pretty good as well. But Smash for Wii U has a horrible Classic mode, a Mario Party mode nobody asked for, a worse Tournament mode and an awful replacement for Break the Target.
The Great Cave Offensive is one of the, if not the Worst stage in the series.
's moveset not representing the "Toon" Zelda games. Toon Link had so much potential for an unique moveset inspired from the Wind Waker and the other games he appeared in.
How the Metroid and Donkey Kong series have been represented in Smash 4 compared to Fire Emblem.
There might be more but I can't think of anything else at the moment.
