How they fucked up Ness:
His Yo-Yo smashes (Dsmash and Usmash) have decreased range and the Yo-Yo no longer trails or has a hitbox during the charge of the smash, they're also much slower.
His Dair is harder to sweetspot than it's ever been, has more startup lag than it's ever had and has more landing lag than it's ever had.
His PK fire has massive amounts of endlag to the point where it's almost ended by the time you can move again, it doesn't activate on shield again either and it's very easy to DI out of and the hitbox is smaller.
PK thunder1 has increased knockback (big whoop) but it still doesn't go through people and the distance traveled by PK thunder2 isn't very far.
PK Flash is so, so slow at moving horizontally, it goes practically nowhere and takes forever to get there.
PSI Magnet still does nothing if the other player has no energy pojectiles.
His dtilt has a chance to cause a trip, but if it doesn't trip it causes neglible hitstun, useless move.
Fsmash can't be angled any more to use it as an edgeguard.
The only seemingly good things about him are his dash attack, ftilt, fair, nair, uair and possibly his side smash.
He's had a load of nerfs since Brawl, where he was already bad, and fuck all to compensate for it.
Trying to play Ness in For Glory is the biggest uphill struggle I've ever had in smash, especially against sheik, ugh.
I just don't understand it, I don't know who played Ness and thought "Yeah, this is good enough". They probably thought he was overpowered or something ridiculous as well, that's the thing that annoys me, that someone out there thought that this was actually a good excuse for a character.
Yes I'm mad, I fucking love Ness and they always make him complete dogshit but this isn't even good enough to be called that.
