It's all about thresholds, dude. Lapis's attack steroid is "only" twice as strong as what Uzume does but that's a big enough difference that shit gets thoroughly crushed. It makes it extremely hard for the devs to design maps around the assumption that they want to challenge Lapis owners but not bone people who don't have her. I can easily imagine a future where she's a default anniversary ticket selection alongside Black Iris because high tier content just kind of assumes you can do that bullshit. The alternative is that she continues smashing maps.
