3DS vs. Wii U
I agree with Amazing Ampharos that one form of smash four should win out, and be supported, and that no one should be butthurt about letting the other form fall wayside. I'm not totally convinced the console version is going to be that winner though. There's various reasons I think the 3DS could possibly be the better platform, but it's sort of irrelevant, we'll see when we get there. Supporting too many forms of smash can put a drain on resources and I don't condone going for both.
So I agree in spirit.
Pitfalls of Additional Options
Here I disagree, very heavily.
I am not opposed to taking the smash game we get handed and playing it as it is, altering the default rules only as truly necessary.
I'm also not opposed to taking the smash game we get handed, spending a few months fiddling with the settings and making drastic ruleset changes that impact balance, and then freezing those changes early in the lifespan. Whether it's damage ratio, timer, custom movesets, stages, food on low yo; any aspect of the game that is easily modified in about two minutes before a match.
What I am opposed to is doing half of each, which is what you propose. What we know so far about the default rules is FD only, no items, no custom movesets. I don't recall your position on items, but you're arguing that we adhere to the default setting on custom movesets in order to avoid struggles between changes seeking to buff and nerf characters, but in the same breath suggesting that we have those same struggles as Wario players lobby to get Brinstar legal and Little Mac lobbies to ban platforms.
Direct and indirect impacts have the same result, and the self interest issues are equally present in both cases. You need to pick one philosophy or the other. Either brave the 10,000 forum posts to add variety to the stagelist and the 10,000 additional forum posts to add diversity to the movesets, or the 10 forum posts to determine that none of the versions of FD have a game breaking bug. If you make the effort on the stagelist and not on the movesets, you're going to have Link players coming in and being confused and upset when they aren't allowed to use their super up B to bring them to the middle of mid tier, and rightfully so, because they'll be playing cloggy Link on carefully mixed set of floaty but not too floaty stages that brings Luigi up to the middle of mid tier, and the reason the two will have received such different treatment is because-melee tradition that is not actually improving anyone's experience.
I would actually be tickled if everyone just used the For Glory ruleset as it is, because there's every indication that competitive balancing in beta testing will take place on FD, and it makes it easier for new players to transition into the scene, and it is probably the ruleset Japan will be using (last time around making a fancy ruleset seemed to make us miss enough fundamentals that Japan could fly over here and kick our hides on our own ruleset with just a couple of their players.)
But I'm not wishful enough to expect that to happen, and if it did happen it wouldn't be cause I said anything about it, it'd be because people play enough for glory mode that they decide they don't want to switch gears for tournaments.
I am wishful that I can at least encourage an internally consistent approach to the ruleset, though. If you're going to make design changes to the default competitive stagelist, make similar changes to permitted movesets, gravity, and every other setting there is.
