Mario

Up-tilt does 5(.5)% instead of 6%

Luigi

Side smash does 21% instead of 19%

Peach

Don't see anything different

Bowser

Bowser dies first when you Side-B

You can Up-B right after Bowser dies

Bowser's Down-tilt's second hit seems harder to land

Rosalina players, use B to get luma back..... FASTER??? O.o

Good to see that they're making changes!

Fucking hell, are you serious? Fuck you Nintendo! That doesn't even make sense! They're on bottom! Bowser still wasn't that great this time around, but that made him worth playing to me. They fucking ruined that now. Bowser could have been a major contender competitively this time around, but no, he's going to be mid tier at best now.

Thats a good thing bro, imagine you playing mario, me bowser. 2 lives, you kill me, then im at 150% when i take your first stock, i run to you side b, i win little+cheap effort. 

This is good^ :)

It's cheap, but not inevitable. If I allow that to happen, it's my own dumb fault. I say it's bad. And again, Bowser was already mid tier at best this time around, and now he's going to be even lower.

Being able to up-B from the bottom of the screen wouldn't help in final destination, though, except maybe for Pac Man and Villager.

To make negative changes to those characters (asside from Bowser's side B) is just awkward. Guess I better see what they did to Pac Man as apparently no one is safe.

So many people spam side-b at one stock when bowser. It's like the only cop-out he has to these people when they are at the stock disadvantage.

NO GOD NO.
