I want to bring this up even though we don't know yet but...
Having an "official Smash League" sponsored by Nintendo and everything in Japan might create a disparity where people who participate in it think, that is what competitive Smash should be since "it's official".
If it doesn't follow a similar format to what the rest of the world uses, then we suddenly have this weird items on Smash league that gets supported by Nintendo while the competitive scene that's done all the work to keep Smash as a competitive game alive for the past 17 years gets told to continue to fund their own prize pools both internationally and in Japan.
Which is fine obviously, I didn't expect anything from Nintendo regarding tournaments, but that's such a weird move. I really hope people in Japan realize that this is just Nintendo's league and not what most people want out of a competitive game because losing your grand finals to a bobomb spawning in your face...Isn't fun. RNG isn't fun in competitive environments. I don't wish to be a purist about this, but there are tons of incredibly powerful "YOU WIN" items and Final Smashes that just don't show skill. If only weapon-type items were on like the beam sabre, or the fan (and there were no fan-infinites) then...Okay, fine. I can see some skill being involved within the randomness.
But with some Assist trophies and Pokemon being what they are, I can't see this being an interesting competition and, at most, a fun spectacle akin to watching people play Mario Party or something.
Which is fun, but arguably not a very good way of gaging who's good at Smash, is it? And if it's just this "We want people to play with items and FS Meter because it'll be fun" event, then cool. But it'll confuse a lot of players over in Japan into thinking that this is "officially the best way to play" when - and AGAIN: Not trying to be demeaning - the players of Smash have had the opportunity to play with items on, and have decided against it for aforementioned reasons.
Not trying to be a negative nancy but I don't see the point behind this. Seems like a weird, uninformed and oddly random first step by Nintendo/Sora to further competitive play, which actually won't help that, and might actually divide already vocal Casual vs Competitive players even further. But we'll see. Maybe it'll just be a fun item event thing Nintendo does and that's it.
As has been said before, I highly hope Sora doesn't suddenly think they struck gold and forces EVO and other Majors to play with "The League rules" or not at all. That'd blow and be incredibly weird. If they can coexist I don't mind this, but it's a weird move IMO.
