>>539425947 was worse... until Zygarde got banned. It would've been way better, but Smogon was afraid of bans that gen because of the backlash of banning "too many" Pokemon. Magearna, Ash-Greninja, Lele, Koko, and Toxapex all should've gotten banned.
8 was a mess before Crown Tundra. Toxapex was too strong, and Smogon was still pussyfooting around bans. By the time Crown Tundra released, the meta had settled and there was quite a variety of offensive teams to choose from. Rain, hyper offense, bulky offense, and even Hail were all viable. Melmetal probably should've been banned, though.
