Yeah, the LinusTechTips forums once went insane in the off-topic thread and usually, there are heated discussions as people argue about Intel, AMD, and Nvidia parts. I remember the BF3 forums getting so bad that I think EA just deleted it and made a new one. The DMC forums were all right when I was there, people who didn't like DmC just stayed away and talked about DMC and vice versa. Some people did discuss it civilly and that's fine.
Considering SSB4 Falco's current situation, I doubt there's going to be a lot going on until something wild happens like let's say some Falco player wins the entire SSB4 tournament at Apex, but I doubt that since it's early and people don't know everything about everyone. Heck, aren't they still discovering things in Melee, Super Mario 64, and more?
Since SSB4 was released and people played Falco, people just dropped him except for a couple of dedicated players. Meta Knight players dropped him because he wasn't OP anymore, but some stayed because he wasn't OP. Marth is more or less the same except numerically in the game's code. So, he's toned down compared to Melee and Brawl and can be played similarly except for things like short hop, double Fairs or using Dancing Blade to recover.
Falco essentially became this weird mishmash of Brawl Falco and Wolf which doesn't work well because Falco never had Wolf's aerial mobility and attacks that covered the ground and moved him. It's like if you took Dr. Mario and gave him Wario's moveset. Oh, Dr. Mario gains a better recovery and perhaps stronger moves, but Dr. Mario doesn't have that mobility Wario has and Dr. Mario's moves are fast while Wario's is slower, but that's fine because it works with Wario whereas it wouldn't work well with Dr. Mario. Can he be viable? Sure, but it's just weird.
Anyway, I bet that Meta Knight and Marth would have more activity, Hell, Marth, Ike, Lucina, and Robin are active in a sense that they can talk about Fire Emblem tactics, story, and such. What are you going to talk about with Falco? Not much since recent games were just remakes and there's not much to talk about. Seriously, what strategy do you have in Star Fox besides shoot, barrel roll, and win?
That being said, I'm not going to slack off since I do want to prove that Falco isn't trash and nor is anyone in this game for that matter.
