Alright, I been dissecting videos and there are a few, key things you guys should know (saving best for last).
#1 Dash attack REALLY kills. In a recent video, it sends Chrom at 67% out a decent ways. And it straight deletes Wolf who was at 150% like he got hit with a Fsmash and the move was stale at that point. This is, however, for the beginning of the move. The longer Wario travels, the softer the move becomes. I'd estimate it kills at around 115% or so. This will become very important later.
#2 Usmash's Hitbox has gone full Mario. I now no longer stops at like 70% of the arc. It should have a metter time hitting people in front of him
#3 Nair's hitbox is not exactly better per say, but if you all remember, the first hit of nair came out at frame 4, the soft hit at 15, and NOTHING inbetween, making it an easy disrespect and tough to use. Now, the Frame 4 Hard hit last the entire spin animation until the soft hit comes out. This makes it a much, MUCH more oppressive tool.
#4 The universal buff to jumpsquat means his OOS game is on point. Aerial out of shield is something to really fear from this man.
And lastly and most importantly (and I am not exaggerating when I say this is a game changer
#5
FAIR
TRIPS
I've seen this happen twice. Once to a Ness who was recovering from PK Fire, and once when a Chrom whiffed a Fair. The Chrom was at 63% when this happened, so I don't think we have a DK Dtilt situation where it stops tripping at percents where you could land kill confirms. There are two things that could cause this to occur. In both cases, the opponent was in the endframes of a move, and Wario hits them square in the head. Ness was hit from an OOS reversal and Wario landed when Ness was on the floor. Chrom was hit from an already aerial Wario, and Wario was able to act while Chrom was still in the slipping animation. In the Ness Scenario, you might be able to connect an Usmash or Dsmash with the amount of available time. In the Chrom scenario, Fsmash easily, maybe even a semi-charged Usmash or Dsmash. DEFINITELY Waft in either circumstance
