>>31393617That idea is basically an Other Meta, since any respectable battle simulator shouldn't touch the raw stats and values of what you battle with. Only thing that Smogon is guilty of directly interfering with is the Sleep Clause, since in-game, using another sleeping move won't fail if something else is sleeping, but that's something most people agreed was a price to pay.
>>31393565This system also means that if Pokemon received different values based on how good they were, some even ridiculous costs just so that people wouldn't use them, then it's not really too different than Smogon's system already. That, and like people already mentioned, would be easily exploitable since msot shitmons can perform at least one task well (Focus Sash lead, Scarf users), in order to support that one very expensive mon so that it sweeps the opponent's team. It doesn't promote variety and people using their favorites, it promotes min-maxing.
