Paralysis is 25% chance to flinch and slashes speed
And you can inflict it with a move with insane distribution (thunder wave)
40% may seem like a lot, but it is only 15% above that Paralysis baseline, and only has such guaranteed odds with a handful (<5) pokemon and a handful (<5) moves under a guaranteed (1) ability. You telegraph HARD that you are going for flinches, and half the pokemon that can do it are SLOW. Meaning that even if they have the flinch (40%), they must ALSO find a way to be faster or the flinch does nothing.
You are going very, very, very narrow for a 40% chance to have your move make the opponent skip their turn.
Smoglets just can't handle rng, or builds assembled specifically to utilize it. They want comebacks and upsets to be 100% tied to skill, like chess, without room for chance.
