DISCLAIMER: I have not read all 4000 posts, but according to the notice on the front, did the minimum requirement by reading the first post.
Second disclaimer: I am not fully decided about my stance on Melee vs. Brawl.
Now, suggestion: Perhaps Brawl's metagame is going to come a lot more from stage opportunities. This may mean that our stage banning might need to be a bit more relaxed. I am currently working on a stage strategy for Ness. Currently I have developed an extremely long list of advantages and opportunities that Ness has on Green Greens that few or no one else has. Perhaps this is where real competitive Brawl lies. Metagame is still being worked on and Brawl might have a few tricks up its sleeve yet. Not all ATs are found yet for Brawl, there are more being discovered. This is the same with Melee. Although people claim that all ATs were found in a month this is not true. Not everything about the YYG was figured out until much later. I know that's more of a glitch, but I consider it an AT as it is still used in tournaments to win. People don't use the black hole (I hope) to win in tournaments.
Furthermore, the ATs seem to be much more character specific. For example: Lucas' zap jump, Ness' PK jump, the ICs chainthrows, et cetera. There are few advanced techs that are universal. This may develop a much more character focused style of playing. I think this is worth being considered.
As characters and stages are much deeper things to be looked into than the general game mechanics (as far as ATs go), more will need to be discovered before real the real judgement on competiveness of Brawl can be determined. Also, metagame does need time to develop, and the more brilliant minds have at least seemingly given up on Brawl. This does not help us at all.
All of that being said, I'm almost 100% sure Brawl will never be as competitive as Melee. But I'm not fully convinced that it won' t be better than Melee. Brawl fixed a lot of things that Melee needed fixed (less emphasis on recovery, more balanced characters, grabbing the stage from both sides, fluidity of the game), and thus Brawl should not be completely thrown out the window. Now I still don't think that Brawl will be as competitive as Melee is, but I think it can get near that level as metagame continues to develop. Already I have seen a ridiculous development in Brawl's competition in the past month or so. I in fact gave up on Brawl for a while due to the lack of competition until I saw more competitive players. I am currently only playing Brawl competitively, but I play all three smash games.
Now, the reason why I endorse Brawl being stuck with is because eventually SSB4 will come out. It's bound to happen no matter what Sakurai thinks or says. Companies want money and they know they can get it from this game. Now I think they're starting to realize the mistakes they made with Brawl, but I also think they should not underestimate what they did right in Brawl. Sure the characters are too floaty and there is a definite lack of hitstun, but the game was made ridiculously fluid. So much more can happen now in a fight in quick succession and much freedom is allowed with Brawl's game mechanics. This is a huge improvement and should be recognized. If we just stick to Melee they might give up on making SSB4, assuming we'll all just stick with Melee.
Now I don't think this should happen. I believe the next game can retain all of (or most of) the improvements from Brawl to Melee AND recover the competitiveness of Melee that was lost in Brawl as well as the more character-specific playstyle of Brawl as well as the more balanced characters.
So what would we end up with?
A game that has more characters than Brawl, is as competitive as Melee, retains a balanced roster, has better hitstun, is more fluid, has incredible depth of characters that provide many character-specific ATs, stage-specific strategies, keeps all of the improvements of Melee to Brawl, fixes Brawl's mistakes, and has no tripping (yes, this needed to be listed on its own!).
So, in order for that to be achieved, Brawl's shortcomings need to be stressed while not abandoning it. This way a new and better game can come out that is, in a way, a mixture of the two, allowing for balanced casual and rigorous competitive gameplay. That is why I am in the defense of Brawl.
And plus, if the whole competitive scene flocks back to Melee, SSB4 might just be some cheesy game which has no depth at all. Sakurai would have succeeded in his attempts to destroy the competitive scene and we would not have a better game. If we show that competition exists even in Brawl and do not give up, the only way to get rid of us will be to appease us and the casual crowd. This, I believe, can be done.
But for that to happen, the competitive scene of Brawl cannot be abandoned.
Who's with me?
