If that statistic is right, Kyd, then you need to stop talking to so many whiners. Lack of Melee techs are not the real problems with Brawl's game engine. It was a bit of a shame to lose some of the things we had been accustomed to, but who cares? As long as Brawl stacks up the same competitively, through different means, nobody really cared all that much. The problem was that it didn't.
I'd LOVE to call you out on it. First off, though I don't hate Brawl, I do think that a lot of poor decisions were made in its production that led to an end result much less than what it could've been. And I do not think that because wavedashing and L-Canceling are gone. Also, there was nothing even slightly glitchy about L-Canceling, it was as intended a feature as jumping. Some arguments can be made towards the "intendedness" of wavedashing, as well, but I won't bother because they're not as strong. They can at best prove the awareness of wavelanding during production, which doesn't really say much about intent.
Combos aren't, in themselves, the problem, no. All of the changes that have almost wiped out the ability to combo however, are the problems. Lower hitstun? Really? That's defensible? Why should a defender be able to react after being hit before the attacker is? If the advantage goes to the defender in every confrontation, there is no incentive to be the attacker, the most important principle of a fighting game. That's how a fighting game progresses, because the defender needs to overcome the attacker and become the attacker in order to win.
In Brawl, the defender doesn't have to become the attack to win. They can just trade hits anytime they let themselves get hit, and perfect shield for a free hit the rest of the time. The deck is stacked in favor of the defender, so why should anyone attack? What's the benefit?
Edit: Oh, and in response to your sig... Yes. Yes there was. So.. you're wrong. *shrugs* Misrepresenting fact, unfortunately, does not really prove anything.
