I understand this but still find it nonsensical to ban things that are, at their core, "noob strategies" which cant reliably work within a match let alone a set and let alone a tournament. I'm not saying Smogon is perfect but I think they generally have good reasoning for the brunt of their decisions.
I also think its part of the learning and bettering process of the players in the game to learn that relying on luck won't get them far and that bad gimmicks are also not gonna get them wins outside of "perfect storm" circumstances.
It won't affect me personally (outside of being sort of sad at the loss of the fling kings rock gimmick) because relying on luck is still bad no matter what, but it does feel unnecessary.
