To preface this post, the "staleness" of the Little Cup metagame has absolutely no bearing on this case. The current metagame, your opinions on it, and whether or not you think this will "make Little Cup better" by putting two more Pokemon in the tier have absolutely nothing to do with the decision made by Elevator Music or me, and has absolutely nothing to do with the acceptance of this proposal.
There are three conditions that need to be met for this proposal to be accepted.
First: We must accept that banning part of a Pokemon is acceptable in Little Cup besides extreme cases, which requires changing our vision of Little Cup and how we tier it. Non Pokemon bans in Little Cup include: Sonicboom, Dragon Rage, Moody, and Berry Juice. We also accept the OHKO clause, which bans the use of moves Sheer Cold, Fissure, Guillotine, and Horn Drill. The moves, Sonicboom and Dragon Rage, are the epitome of an exception. They are unanimously broken on any instance they appear in a moveset. Likewise, we adhere to the OHKO clause, which also bans moves--any arguing over this aspect of the banlist and it being representative of an over complicated ban list holds no bearing. Moody is likewise a terrible exception--it brought the entirety of Smogon to its knees, even being resulted in a ban in Ubers. Finally, Berry Juice is not an inherent part of a Pokemon. It's equivalent to the Soul Dew Clause in OU. Banning an item is not inherently problematic regarding our vision--it is not an inherent part of a Pokemon like the ability Speed Boost. The current ban list does not hold any inconsistencies with our vision with the tier--Speed Boost would not fit right in, as many of you seem to believe. It would the odd man out on so many levels.
Second: We must accept that Speed Boost is an acceptable suspect, having agreed to the first condition. I disagree with that based off of my views on when to ban a part of a Pokemon. I recognize the current camp's claim saying that "In BW2 LC in a vacuum, Speed Boost is only available on two Pokemon, both of which are banned." However, I do not consider that coincidence, and the poor reasoning that has occurred thereof, as an acceptable reason to consider this case. I very much adhere to the "if we ban a part of a Pokemon, that's because it would be broken on everything with it." We can accept that we have not banned Huge Power, even if Meditite has it, due to Azurill having it. Azurill is stupid, even with Huge Power. Thus, Huge Power is not intrinsically broken in Little Cup--Meditite with it is. Meditite, with its excellent dual STABs, access to STAB recovery, and good speed, in tandem with its insane Attack stat after Huge Power, is broken. Meditite as a whole is broken. We can break the Meditite example into two parts.
1) Assume something shitty like Wurmple got Speed Boost. Wurmple would still not be broken, even with Speed Boost. As such, we can tell Speed Boost is not inherently broken. This is different than the Moody case, where (almost) everything that gets it would be broken with it, thus illustrating it as broken. Furthermore, this is consistent with our ban of Vulpix, not Drought. While I would be receptive to banning Drought as universally broken in Little Cup, if something stupid was to receive Drought, such as Caterpie, we can say that the crux of using shitmon for Drought is too much for the benefits that Drought provides, as we have to contend with Snover and Hippopotas to maintain it.
2) The Pokemon that are banned "due to Speed Boost" are banned due to a combination of traits. As we can basically assume Speed Boost as a whole is not a broken ability, we must consider the banned Pokemon as a whole. Yanma, with its excellent dual STABs, 4x resistance to Fighting, incredible Speed, access to Hypnosis, reliable recovery, good bulk with Eviolite, and access to Speed Boost makes Yanma broken. Carvanha, thanks to his excellent dual STABs, insane mixed offenses, great Speed, and access to Speed Boost make it broken. Their banning cannot solely be attributed to Speed Boost. It's a combination of factors that include Speed Boost. Thus, I don't believe we can subjectively suggest Speed Boost is the end all be all of these Pokemon--if we banned Air Slash and Hypnosis on Yanma, Waterfall and Crunch from Carvanha, or Drain Punch from Meditite, but kept everything else, I can guarantee they would not be considered broken. Should we do this?
Third: We must accept the policy ramifications that occur due to accepting this suspect. We must accept the pains of beginning suspecting again so close to XY. Furthermore, by bringing this suspect up, we would most likely find other abilities and such that we would want to suspect, making it very possible that suspecting would be occurring all of the way up to XY's inception, and having to focus both on BW2 and XY at the same time. That would be a nightmare. Finally, we need to consider BW2 revamps and the current activity of LC C&C. We just went through a fuck ton of revamps--we would have to go through just as many, based on these two additions (assuming Speed Boost gets unbanned, and Yanma + Carvanha enter the tier). We don't have the "resources" to do so, leaving our currently mostly updated analyses updated right before we transition to another generation, thus possibly leaving them permanently outdated.
This is a subjective tiering nightmare that forces us to adopt new policies regarding LC tiering, and forces us to accept a ton of things that I don't think makes this even slightly worth it as a consideration. I disagree with Speed Boost's worth meeting any of the conditions I listed above. Just because we're bored of Little Cup does not mean we throw everything out the window. Ultimately, the decision rests on mine and Elevator Music's shoulders. Neither of us, for the reasons I have listed, believe this is a good idea.
