Sorry, I haven't really read much of the last couple hundred pages
. I read the virst 20 or so, and I guess I will give my input on this subject. Certainly I shouldn't be considered an expert since I am very new to the competetive smash scene, but I have read thousands of these debates and I feel that I have a decent grasp of what is going on, especially since I have identified with both sides at various points in time. I'll just point out some flaws that I have seen in arguments, some have been in this thread, and some have been in others, but I will just say it all here.
OK....
First, I here a lot of people saying that there is still time for people to develope new techniques and it has only been a few weeks/months. Not that I know very much about finding techs since I spend hours in training around, but have yet to find anything new, but that is besides the point. It will not matter. Even if we were able to find something like wavedashing or if it was still in brawl, I don't think that it would do much for the game. As has been discussed, the problem with brawl boils down to the lack of hitstun. The whole push-pull and punishment is very important, and you can go back to page 2 or 3 to find it. All that wavedashing does is help approaching, and evasion. If we could wavedash we would be able to approach safer and faster, but that would not change the outcome. There would still be an exchange of one or so hits and then we would be back to sqaure one. It would also help with evasion which would only make matches even more dull.
Second, I here a lot of people say that they don't like combos and advance techs because they create a large gap between the competetive and casual scene, but I don't believe that at all, and this comes from personal experience. I played 64 and melee for what is it like 10 years? never knowing about l-canceling, or wavedashing, and I still had a perfectly fun time. Sakurai claims that competition doesn't matter and that people should have fun, but I don't think that justifies him putting in tripping. I don't care how casual of a player you are, you will not like being tripped or even others tripping. It isn't fun to play a game, even at a completely casual level to know that you won a game just because your oponent tripped.
I may reply with more later, but first I have to eat. Sorry if my opinions are completely misguided and wrong, but it is just what I have gathered from my countless hours of lurking.
