lol I'll use dsmash as an example because I'm sure you know what that is
Except Luigi's up B has crap range and Luigi doesn't run fast enough to close the distance. You'd only be punishing really, really laggy moves...which the opponent shouldn't be using in a matchup where all they have to do is play campy.
Only it's easy to do because Luigi doesn't have great range (well, maybe his bair). Luigi pretty much has trouble against anyone that outranges him (disjointed range of course, or if they outspeed him too, though there are some exceptions).
I'm a little confused on your post.
I never mentioned UpB and don't find it to be a big part of his game. It's really just something to watch when playing against a Luigi and can situationally get him a quick stock lead.
There are better things to do than that, and they land all of the time. Example, dsmash
But most of the high tiered characters don't actually need to set up finishers, because their finishers are fast enough to simply serve as punishment (or if they have little ending lag you can just throw them out every now and then. Like MK's d-smash or Snake's up tilt).
fsmash, usmash, nair and of course...dsmash?
lol seriously, don't support Luigi as a way of showing he's bad.
At any % they're some of the best moves, made even better by how they set up more of each other because they fit Luigis game so well.
Quote by me - That's EXACTLY like saying Marth > Snake because his sword out ranges his tilts.
Quote by you - Only Marth's range advantage on Snake is actually pretty small, while Snake's power advantage is extremely large, and their attack speeds are about the same.
Exactly. Thanks for backing me up without understanding what you were doing at the time lol
Attack speed +
Power +
One thing called "Luigi Down Smash" has just under the range of something else called "Marths Foward Smash". Sure Luigi has a disadvantage against characters with large disjointed hitboxes and fast moves in the air to match his like G&W, MK, TLink and Marth. After that nobody has much on Luigi aside from the camping game which isn't exactly an end all thing anyway. If Luigi gets passed that they're in trouble. That's the whole reason it's such a big factor against Luigi, it's just that important for them to win against him.
And why is it that Sonics are always the ones that don't know anything about weegee? Do you all have a grudge against him cause everything Luigi > everything Sonic? >;^D
