I know how you feel, M2k (to a point, i didn't gain fame from my skills). But please realize, we play Marth. WaveDash really unbalances Marth. Nearly everyone is unbalanced and Marth shoots up in tier more because of his reach, disjointed hitbox, speed + long/smooth WaveDash. I love it but it's really unfair for some of my friends who are biased towards...well you should know...Mewtwo or Pikachu. I don't say wavedash has to be out, but Sakurai really wants to balance the game. He doesn't want crappy low tiers and top tier to be so far apart.
There's two ways to do this:
1) with wavedash in mind. That means wavedash will be a big factor. If Marth were to come back and had wavedash it'll probably be like Link's: short and pointless since Marth already has other advantages on his belt (speed, hitbox, range). Trust me, if wavedashing was in, Ike would have a long one to balance it out (as contradictory it sounds). Wavedashing can make speedy characters even speedier and very little to slow characters (Ganondorf, Link, Bowser) The problem is, not everyone will use wavedash and it'll make characters highly unbalanced in terms of casual play if he only caters to us "purists"
2) without wavedash. this is only way to balance both casual and tourney purists. Realize melee is pretty okay balanced at a casual level but when you put wavedash in the equation it really makes Good characters top-tier (Marth, Fox, Falco).
I understand your rant, since you've excelled at this. WaveDashing is an integral part of Marth play. But look at Link. He doesn't really need wavedashing to be competitive (Aniki is the example). Sakurai can follow that example for everyone and make sure everyone has correct advancing options and retreating.
Brawl is not Melee - Wavedash
Brawl is Melee - Wavedash + Necessary tweaking.
Those said tweaks will make it balanced.
yeah wavedashing really unbalances the game. I hate how when I'm Fox and my opponent is Mewtwo and he uses his superior wavedashing to defeat me. oh wait that never happens. saying wavedashing is unbalanced and needs to be taken out is so stupid. SSB64 was way more unbalanced than melee was and it didn't have wavedashing.
