I mean, it was an issue in the past, but Ultimate pretty comfortably supports fully functioning 8 player Smash now.Depends on what they want to do with Smash. If we end up seeing a hard reboot of the franchise in the next game, we might see the end of Gamecube controller support. The Wii had a lot of controllers, which necessitated Brawl's support for just about everything, and since the Wii controllers worked with the Wii U, they continued the trend. Since the Gamecube controller has been able to haunt every Nintendo console since its inception, I think they keep it for tradition at this point... But if Smash stops growing and refocuses, is there tradition to keep?
8 player is definitely emblematic of the Wii U era, being the "hey look at how cool this feature is, it's unique to the Wii U version of the 3DS game you already have" of Smash 4... And is probably unfortunately here to stay. It's not something I enjoy and it has actively been a detriment to the game in the past and I think it probably still was this time. There's always going to be a limit to how much crap you can have on screen at once and if Nintendo insists on keeping their hardware a generation behind "standard", it's going to chug under the weight of what's going on in a Smash game. I have to wonder if they brought it back because it was an easy feature to port over and add to the "everyone is here" shtick or if they just like the idea of it.
It's really just meant for like, parties and whatnot, not meant to be taken too seriously or put too much thought into.
