Light characters aren't nearly as good as they used to be. Knockback on all lightweights is reduced signifficantly. So all you Fox, Falco, Sheik, and Marth people from Melee are going to be in for a shocker. A good heavy or even more deadly a lightweight counter like Lucario can really show you what for in Brawl. This goes for those of you looking at Meta-Knight and Pit too. Light and fast =/= uncontested victory anymore.
