EDIT: Adding the quote here
I mean, I picked up Pikachu... and like, then ban ICs too, because I'd much rather pocket MK than pocket TL (trying anyway), ZSS, or Peach (or be stuck playing Pikachu or Falco the whole set against ICs). MK is a very helpful check on ICs in my opinion, but that's besides the point I guess.
Like, you can still see people pick up Falco and Snake now. Also, I'm at least partly convinced banning some characters just slides the best characters down - Marth would have one bad MU (Dedede) and Dedede would lose his (second?) biggest issue (both with ICs gone), while Falco can still chain-throw the **** out of people and has lasers. And Snake has utilt + 20% damage ftilt. Like, now people just pick up Falco, Marth, Snake, and Dedede instead (and many probably also pick up Olimar and Diddy Kong, but I'd argue they require more work to be played competently (because it's the newer players doing this). Or if MK's gone, people REALLY start picking up ICs. So I'm not sure how a ban fixes the problem? (I'm not familiar with the time MK was banned - if someone wants to tell me this is all empirically denied I'm more than willing to listen but want statistics just so I can compare myself).
This is the situation in Melee you ID'd [parallels to Brawl in brackets] - Fox/Falco/Sheik/Marth [MK maybe ICs] beat nearly everyone well below them, except Peach, Jigglypuff, Captain Falcon, and Ice Climbers [characters 2-9 or 2-10 on the list] keep up better (so do Axe and Shroomed and maybe Kage) [Trela] so you'd have to ban at least the top 3 and probably all 4 to fix it there. But then CF, Peach, ICs, and probably Doc become broken [Falco, Snake, Dedede or ICs, Marth], so do you ban them next?
Second edit: I do not understand how the video relates to what I said, but whatever.
