Stop being bitter. Nintendo is first and foremost a company. Their goal is to cater to EVERYONE, not just those who like "hardcore" gameplay. Stop thinking about yourselves all the time. Brawl is a game that is supposed to be for everyone. Like it or not, the mass majority of Brawl players will be casual players. I know we all love wavedashing and advanced techniques but if you honestly think you can surpass Sakurai and his team in making the best smash game ever, then you must be sadly mistaken.
Learn how to model, skin, texture, shade, rig, animate, light, render, code, fix errors, fix issues with models, code in gaming mechanics, fix glitches, and do -everything- else that team has to do and then come talk to me. I hate people who are just all talk.
Don't get me wrong, I will miss wavedashing and some of the older techs, but there will be new techniques and new surprises to uncover in Brawl. It's not melee. It's an entirely new game.
Sakurai and his team DO know what they're doing. Accept it or not, they will -always- have a head up over all of us in regards to smash. They MADE the game for ****'s sake. Brawl will not be lacking in the advanced/competitive department. They're just trying to make it more user friendly for people new to the series or who don't care about competitive play.
In a simple phrase:
Get over yourself.
