Keep in mind that Sakurai never intended Smash to be played competitively
at all. From the interviews he has given, the priority has always been the "casual" fanbase that prefers free-for-all items-on timed-match madness, with 1v1 as a secondary concern. Every competitive standard we have in place today is purely the result of the players themselves making the most of the optional settings given to us. I would not put too much stock into what the developer "intended" versus the reality, especially since none of us were actually involved in the development of the game and cannot know for sure how the balancing process went down.
Also, the balance patches we've received there
have been changes made to custom moves; just not the ones that are currently in vogue to complain about. So they're giving
some sort of attention to custom moves, even if it doesn't address the immediate issues of the day.
Several points I'd like to hit on:
1. Changing
how a character fundamentally plays is NOT necessarily a bad thing. Vanilla Palutena is an overly-defensive character with (non-recovery) specials that ranged from "use this maybe once a match, if at all" to a rushdown aerial speedster with a lethal grab game. I doubt anyone would find the former more exciting than the latter. Customs-on Rosalina becomes
more aggressive, and given the reaction to her effectively-defensive playstyle championed by Dabuz at Apex, it's difficult for me to see why taking away her aggression options improves the game.
2. How would a character that "makes wins off of good reads" be considered "low-risk". Isn't the requirement of making reads to get hits & kills the definition of a "high-risk" character? Did you mean he is a high-risk low-reward character in vanilla that becomes a low-risk high-reward character in customs, instead?
3. I am not familiar with the Bowser vs Villager match-up, so would you mind explaining why dash-slash (a move that I thought was primarily used from the air) is invalidated by the villager's trip sapling (which is used to force opponents away from the ground).
4. Ultimately, it seems the point that you are trying to make is that match-ups become a "whoever has the better custom wins", but we're really not seeing that in tournament results. Have any custom Bowsers been dominating their locals (never mind anything greater)? Villager has been performing well, but he has also been placing highly in vanilla too, and his top-8 placings haven't changed too much with customs. I'd be interesting in seeing which characters you think were the biggest winners from a customs-legal meta, and comparing their tournament results and more importantly how their match-ups changed. Which match-ups go from "these characters had an even chance" to "this character now destroys this other character" with customs? Mewtwo has only been out for a month, and his viability was already being seriously questioned - few players are giving a better impression of him than "mid-tier", and this was
without considering the Bowser-matchup specifically. (Keep in mind, if we're going to count how many match-ups become slaughter-fests with customs on, we should also be counting how many match-ups are slaughter-fests
without customs.)
A character's reliance on a certain move comes down to how well their opponent can punish that move. The strongest options in the game are the ones that are considered "safe", where even if your opponent performs optimally their opportunity for punishing is limited. Kong Cyclone is considered as strong as it is because it is believed to be un-punishable thanks to the combination of the landing-lag cancel and super-armor, but even KC is starting to
show cracks.
Also, after listening to Zero's post-DVDA victory interview, some of the customs complaints are quite perplexing. This is the first time I've seen
anyone complain about Luigi's green-missile customs. Heck, most high-level Luigis barely even use customs. Allegedly, Zero was taking issue with the ease with which that custom lets Luigi make it back to stage, invalidating Sheik's edge-guarding and thus removing a section of the gameplay that he found enjoyable and healthy for the meta. But, if Sheik's edge-guarding is so strong against Luigi, then aren't Luigi's customs (helping his recovery) opening
more gameplay options, at least from the Luigi player's perspective?
