You know what I hate about the logic argument?
"L-cancelling was the cornerstone of Melee's competitive scene. It's gone in Brawl, therefore Brawl will be less fun."
The thing I hate about it is that the depth a game is in the sum of its parts. No matter what you say, however you put it, your "logic" is just a theory/hypothesis to an experiment that hasn't been properly tested. You say this one part is important, and let's say, there's nothing in Brawl that can be used to such an extent as L-cancelling was. At the same time, we can agree that there are new things in Brawl, just not as game improving as L-cancelling. But we can't say that these new things, combined with the old things that are still in Brawl, will make Brawl less deep than Melee, or even so bad that it will become "not fun."
So sure, let's put your hypothesis up there. Let's assume before we test. Let's not believe we'll have as much if not more fun. Let's do all of that. The thing that bothers me, and happens to be what everyone else is saying, is that it's still a hypothesis, completely unproven, and you're just spewing negative emotions all over this board with making your doom and gloom seemingly fact.
And can we stop posting videos for evidence? Especially since 90% of these have really bad players, and the rest are average or maybe a little above, but still getting used to the game. And then you have to deal with the varying landing animations....
Oh, one final thing, looking through the characters, Ganon seems like he's the absolute slowest out of everyone, and in my opinion by a pretty large degree (although he pairs with Ike in being this far off on the spectrum). Take that how you will.
