I personally don't even know how we can even separate the "good" and the "bad" when half of the United states hasn't even played brawl yet. Now dont get me wrong Yuna, i have read many of your post's and I honestly value them more than others. I am just simply stating that, we can't jump the gun. I mean watching video after video seeing some toons amazingly played and then watching another video of that same exact toon being so terrible its almost unbearable to watch. I mean we can sit here and debate a Tier list list all day, every person here can agree, but the Tier lists always change, Melee's did a few times.
With that being said, I also believe there are a lot of toons in the Smash Series now that bring a lot of new play styles to the field, such as Sonic, Olimar etc. I just truly think it depends on style of play. We have a ton of new characters, characters people have not yet learned to play "correctly" characters that are still trying to be discovered. I believe there is no perfect character, and that all characters have a counter, and I believe this because of the character diversity that the smash series has always offered, which is why I learn more towards it than any other fighting franchise. With that being said, I am also truly a believer learning multiple characters, kind of like counter-picking against your opponents character.
I understand where you are coming from, stating that the gap between tiers is larger, but it also seems to me, that many of the characters are good regardless of tier, and judging by the community here, it looks like there is a strong population behind every single one of the characters in Brawl.
