No competitive player has ever said that. In most cases (both on smogon or in vgc) moves with average accuracy 70%-90% are almost always a direct upgrade from lower power moves. Sleep powder is common on mons like Venosaur and that’s because the reward always outweighs the very low chance for the risk. I mean, for Christ’s sake, Ting Lu with fissure epidemic was literally earlier this same year. The quote you refer to comes from the RU-vidr MandJTV who is a casual player rather than a competitive one.
my sw has around 77/97% crit rate there, depending on whether her sig is active. fu xuan has either 90/98 crit rate depending on if her disciple had a stack or not.
Sparkle, and Sparkle. Sparkle is giving like 85% atk because of her trace that wants Quantum allies and e1, and she gives a ton of crit dmg to her targeted ally, and based on another comment she's e6s5. This is a premium Sparkle so the boosts are higher than normal.
sparkles e6s5, sw is e2s5 and in a semi crit build. i say semi bc i heavily focused spd, she’s 174, so her crit stats are mid but sparkle gives me like 270 odd cdmg so its fine.
