Yep, I've actually been convinced. Kudos everyone. Let's not restrict custom moves until we learn more about them--some builds may end up being Metaknight levels of broken, but let's also keep build switching something done by the loser as part of their counterpicking to avoid a situation where the winner of game one switches to a strong build to clinch the set in two games. That just kills competitive hype.
If multiple builds for multiple characters are as broken at Metaknight, it's not actually broken because it puts them on an event playing field. Lets say, in Brawl, Metaknight is Metaknight. Let's say his regular move set was just as good as his custom move set. But let's say, oh, Snake or Marth or someone, had a custom move set that let them 0 to death a few characters. Sounds broken, but what if one of those characters is Metaknight? Now the entire game becomes more balanced become someone has a really good custom move set.
Custom move sets have massive potential to balance the game more than using all standard move sets. Every single tournament player would have optimized their custom move set to the one that works best against Metaknight.
My prediction is the custom move sets Smash4 players will use after a year or two the most are those that work best against the top tiers. Personally, if a custom move lets me combo a low tier, I won't care to learn it or practice with it much, but if it helps me KO the best character in the game, you bet I'm going to use it and abuse it.
Well what's overcentralising? Should all custom specials be played on a character to not be considered overcentralising? For "lower tier" characters, they likely only have a single best choice. Let's say a specific character is overcentralising, is it because of their custom specials? Are they "fine" without it? (really hard to tell).
The truth of it all is that if questions and issues keep coming up in the way of Custom specials, then the fact there are over 600 specials means this will be overwhelming to deal with without obtrusive/hard to remember surgical changes.
I disagree that lower tier characters only will have one choice. From what I have seen of them, the best custom special will depend who your opponent is - both their character and their playstyle. Your optimal choice will be if they are aggressive or campy, heavy or light, etc. Example: Peach's heavy custom turnips deal 20% which sounds pretty crazy until you find out how weak sauce the range is and how slow it comes out. I imagine the heavy turnips will be good against heavier characters and the light faster long ranged ones (also a custom) will be good against faster characters. On the opposite side, if you play campy characters, having a super fast turnip that has extra long range but deals very low damage is useful. I already can envision witch matchup's I'd prefer which specials, and even if Peach is low tier, it won't change the fact that I'll probably want to change my turnip custom depending on the opponent.
Truth is we don't know enough about them to ban them. I just think so far the evidence to me doesn't show a single reason why they should be banned. These fears don't have evidence behind them. Intead of theory-izing, can someone name a custom special which they think deserves to be banned and show some video evidence of why its to bad?
Otherwise, I will say let me ban Greninja because I dont like the idea of Greninja, he seems annoying. Afterall, we get to ban things we don't like the idea of without evidence apparantly.
