Let me explain, WHY, I think they should be out, for the fairness of the community, not to cater to the Pros.
The minority of Smash players know how to pull off these techniques. It's much easier to level out the playing field by taking them out, rather than forcing the majority of Smash players to learn these techniques.
SSBM has sold nearly 8 million copies, even if you assume that every member of SmashBoards and the old Nsider forums were avid Wavedash/L-Cancel users, the headcount combined hardly surpass 100,000
The community happens to be us, people who use the techniques. What other smash forums have the other 8 million smashers?
I would call that a minority. Therefore, I doubt they are going to cater these techniques and glitches to the minority that know them, especially when the profit comes from casual gamers nowadays, which is the expanding market.
These techniques leave the people who can pull them off at an advantage. A decent player and a decent player that knows L-cancelling and wavedashing, who has the advantage?
I hate to say it, but there's no such thing as a decent player that doesn't know how to do said tactics.
I'm sure I speak for many when I say I don't want the Smash Bros. Brawl online community to become that of Mario Kart DS and snaking. Sure, it leaves those who knows these techniques at an advantage, but it leaves every one else at a disadvantage, and is just no fun when you see people zipping around the track at a million miles per hour, just like how it wouldn't be fun for this majority of Smash players who don't know techniques like wavedashing, L-canceling, etc. to join an online match and be pummeled by people zipping around the stage and canceling out the lag.
I'm not sure what to say here, fine, true, whatever, but honestly most of the good people who play this have plenty of friends from SSBM to play against rather than join a random match. I for one will probably not play random matches often at all. If the majority of good players will play each other, then there really isn't a problem for those little kids who want to play the game "how it was meant to be."
Even though you can say "Just learn to do it!" doesn't change that a Wavedash/L-Cancel user is the one with the Advantage because of exploiting something in the game, even if both players are equally skilled, the one doing the exploiting gets the advantage
So, no items, fox only, final destination, mirite? What you are saying here is basically that everything is equal, but the truth is, ie. ssbm, that a Link spamming up b player will most of the time beat a running up to and trying to usmash fox. To be honest, you'd think the fox would wait it out, but unfortunately at the level you are talking about, they would just run right into the up b, especially since they don't have as much control of their characters as advanced players do.
And I'm not saying this because I can't do it, I play SSB64 and Melee at a competitive level and can L/Z-cancel and Wavedash just fine, but when I'm playing with friends and they can't commit time and practice towards Wavedashing and the like...they're not going to be having an enjoyable time playing against someone who does.
If you can't commit time to learning the advanced tactics, why are you going to tournaments? You aren't going to tournaments? Well then why are you complaining to us?
I personally think SSB's experience would benefit from it being taken out, making it so that people like my friends can have more fun with the game even if playing against someone who puts more effort into the game like me. You can accept that you lose to someone because you messed up or you acknowledge that the person you're playing is better than you, it's harder to do that when it seems like you lost because he's exploiting something to get an advantage that you're not. It levels out the playing field.
I'm sorry, my YOU ****ING MORON alarm is going off. Competitive smash IS fun, for us, we don't want to play random scrubs all the time. I'm particularly sure that if a competitive smasher goes and plays against a ton of random scrubs without any good competition, that one lone smasher wouldn't be having much fun always wining. Competition makes things fun.
Those are my two cents.
And those of you who are going to be like "Zomg not again" and flame me, don't bother to post.
