First off, mad props for calling wavedashing an exploit instead of a glitch. At least it proves you're thinking clearly.
Sadly, this is a gross misrepresentation of the Melee community. Melee players do not oppose change, but they do oppose
bad change. When Brawl came out, every Melee player on the planet rushed out and bought it. Everyone was ready to move on. Melee tournaments were on life support for a while. The problem is that Brawl took away movement options and replaced them with terrible things like ledge-stalling. We don't need wavedashing, but we do need ways to move fluidly and inflict mind games upon the opponent. The great thing about Melee is the intricate mix of reads and reactions. Brawl is all reads. Sm4sh brought back some reactions, but it is still quite read-heavy.
I watched both the 3DS tournament and The Big House 4. Sorry, but TBH4 was 400x more interesting. Nintendo is putting in a strong effort to join forces with the competitive community, but only half the company is on board: the game developers still work from their ivory towers and seek to undermine fast, competitive play.
It is fine if you like Smash 4 more than Melee. It is fine that Melee players keep doing what they are doing. Who are you to come along and indicate that these people are somehow defective? What obligation do we have to embrace the new game just because it is new?
Melee lives on because of the high skill ceiling. You are fooling yourself if you think a low skill ceiling is good for the community. Sure, it brings in an influx of newbies for a period, but your top end players start hopping to other games entirely (competitive DOTA/LoL or fighting games on other consoles). Melee is not a walled garden. Several of the top players right now are Brawl natives. (On that note, do you see Brawl tournaments going on? Yeah, me neither...)
So please, spare us your "Sm4sh was made for the open-minded" nonsense. You cannot say that while complaining that the game "requires the use of the unintended exploits like wavedashing". So the dumbed down game is the more "open-minded" candidate? Please... Project M has completely replaced Brawl at events. So, it is in Sm4sh's best interest to be more like Melee.
