>>55768937>banning dynamax, while necessary, set a dangerous precedent that anything can just be deemed broken and banned on a whim, and that fully came into effect in gen 9.Dynamax was a shit game-breaking gimmick that no one with any sense wanted around. It didn't set a precedent though. Terastallization is still around without even the slightest action taken against it. Not even revealed Tera types at the beginning of the match.
And that's a bad thing.
>key mechanics like sleep that HUNDREDS of mons can use without being broken can now just be removed overnight because some tranny doesn't want to ban iron valiant.Sleep itself was busted in Gen 9 because of how violently hyper offensive the meta was. Darkrai is actually a good posterchild for this effect since it was a top tier Uber in Gens 4 - 6 while it was considered a shitmon afterwards because Dark Void got gutted. Why is that? It's because Ubers is insanely hyper offensive, so even 1 free turn can wildly swing the outcome of the game.
Gen 9 OU and UU have effectively become Gen 4 Ubers with their insane power levels. It's not just Iron Valiant and Darkrai that can annihilate your team if they get a lucky Hypnosis off, it's Pokemon like Volcarona, Roaring Moon, Dragonite, Kingambit, Skeledirge, Quaquaval, Iron Moth, Ogerpon, Gouging Fire, Iron Boulder, Blaziken, Ceruledge, Garchomp, and Raging Bolt that can directly convert a singular free turn into a win.
This is largely a byproduct of Terastallization giving these Pokemon a second free turn to do what they want thanks to the mindgames around Tera. Since Smogon didn't want to ban Terastallization due to the Dynamax ban backlash and they didn't want to ban another 10 Pokemon due to Sleep being broken, a ban on Sleep was inevitable. The last gen to be this absurdly hyper offensive - Gen 5 - has also banned Sleep entirely.
