Ok I'm going to tackle a few of these, since I was there last night.
The only other two that I think are misplaced are Gardevoir and Sawsbuck, which are both solid A imo. Garde can do so many sets, whether it be offensive, defensive or even a support set, as well as having an excellent ability in trace, which can make it a fearsome Ludicolo counter by copying Swift Swim, or by doing things like stopping volt switchers with lightningrod e.g. Zebstrika. On the other hand, Sawsbuck has massive power after even one SD on the subSD sets and from my experience always gets at least one kill a game. It's also a good band user, Grass & Normal is a great STAB with Nature Power (EQ) to finish off the coverage as well as bypass Sucker Punch. Hell, if you wanted to you could even use a BP set with SD/BP and either two attacks or one attack and sub. After all of this it seems to me at least that they are solid choices for A, and they more than make up for their flaws which is mainly a somewhat lacking defense.
I disagree, and I will say that they were both unanimously voted B by the 4 people that were there.
Gardevoir- Base 80 speed used to be the gold standard of the metagame, but now it's way too slow to really do much of anything. Gardevoir was great as a jack of all trades kind of Psychic-type: it could go offensive with Life Orb, cripple a wall or sweep with Trick Scarf, or use its passable bulk to support the team with Wish / Will-O-Wisp. Now, it gets outsped by 3 top threats in the metagame (Jynx, Scolipede, Primeape). Its LO set is drastically outclassed by Jynx, who can cripple a Pokemon with Lovely Kiss and then start ripping into teams with its better Ice/Psychic STAB. Its Scarf set is also outclassed by Jynx, because Jynx doesn't get straight up outsped by base 95 Scarfers, and can again cripple mons through Trick or Lovely Kiss. Its bulky sets can't stand up to Scolipede, and Primeape can just U-turn out for a huge chunk of damage. Musharna is your best bet for that role. Even if you use Traced Swift Swim as an argument, Seismitoad is immune to Thunderbolt, and Psychic won't OHKO. All in all, the metagame is really not favorable for it at all, which is why it dropped to B-rank.
The same goes for Sawsbuck really. While Grass is a good offensive-typing, Sawsbuck is frail and doesn't appreciate Scolipede running around everywhere. There are also a ton more Fire-types around, especially Charizard, that outspeed and can easily OHKO. Scarf Primeape is also a thing, and it can either KO with Ice Punch, Close Combat, or U-turn out for heavy damage (might also be an OHKO depending on hazards). Finally, it only speed ties with Jynx, meaning it can't really force it out (especially if Jynx is Scarf). The best niche Sawsbuck has right now is a Chlorophyll sweeper, where it can outspeed the entire meta with doubled speed in Sun, but that requires the significant support of a Sun team, leaving
Bambi in B.
PS: Eelektross is not even close to S-rank, it's closer to B rank than S-rank. Slow Volt Switch is nice, but its bulk isn't all that great and it doesn't get many resistances at all.
I typed a bunch but lost it all :(
Basically I think Audino should drop down to C-rank because it isn't bulky enough and lacks any sort of movepool and is huge setup bait but has a Dual Screens niche, Regirock to B-rank because it lacks reliable recovery and Rock Blast and doesn't help the team nearly as much as Piloswine or Golurk (priority, antilead, excellent STABs and coverage etc).
And Lickilicky should move up to A-rank because it is one of the bulkiest mofos in the tier on both sides, has excellent support movepool, good offensive stats to either break subs as a wall or hit hard offensively, and can surprise opponents with all kinds of offensive, defensive and setup sets which are all usable (Spdef, SD, Curse, Band, Mixed, Cloud Nine, they're all decent sets!). It is the premier special wall and very versatile outside of that, so deserves A-rank imo.
Also Metang in B-rank doesn't look right. I'm struggling to think what it can do, check Jynx somewhat I guess, but it is massive setup bait for nearly everything. For a full stall team it might be OK but it lacks phazing or any sort of threat and not even Leftovers! It is C-rank if generous, but I'd be tempted to stick it straight into D-rank!
Lickilicky and Audino are both B because they perform the same role in slightly different ways, but the fact remains that they're both Normal-types in a metagame filled with Ghost-types and Fighting-types.
Audino is B-rank because of Regenerator, and with Double-Edge it outputs about the same damage as a Lickilicky Body Slam. Regenerator allows it to not have to always Protect after using Wish, since it can heal its own HP at the same time as a teammate's. That alone is pretty damn huge, it frees up a moveslot to use another support move like Toxic so that you can hit Misdreavus coming in.
Lickilicky is also B-rank because it's fat, and can phaze with Dragon Tail, and can Wish pass. However it really needs Wish, Protect, and Dragon Tail on its moveset, leaving only one slot for either Heal Bell, Stealth Rock, or Body Slam, all of which are good moves. The problem is that it doesn't have room for all of them. It's also really easily worn down with smart switching, since it doesn't have Regenerator to heal it when it gets forced out. All of the offensive sets aside from like Normal Gem Explosion are outclassed by either Kangaskhan, which has the same effective bulk as an offensive Lickilicky would, but with a much more effective movepool in Scrappy-boosted Fake Out, Sucker Punch, and Drain Punch, or Tauros which trades bulk for raw speed and power. I wouldn't even come close to calling it the "premier special wall", let alone the fact that in this metagame, pure walls are less valuable than tanks that can hit back hard.
I'm not going to write a full paragraph on this but Metang is solidly B-rank, since it has great typing and great bulk in the metagame, and people have figured out how to effectively use what attack power it does have, through Hone Claws or Psych Up.
EDIT: Oh and to all those who think u-turn alone is enough to keep him S rank, keep in mind that 85% of the time you revenge kill something, u-turn does not have suffcient power to do so meaning it's a 50-50 mind game on weather you'll use cc or u-turn and this mind game can cost you just as much as it can help you which is clearly not enough to make ape S rank.
Why would I need to use a mind game? Early game all you need to do is spam U-turn, until all of the Ghost/Psychic-types are gone. Then you can quickly and easily clean up the opponent. Also, you're ignoring all of the non-choice sets that Primeape can effectively use, like EndRev, Encore/Taunt + U-turn, Fling Fist Plate, and even Rain Dance. I will say that Primeape is on the edge of S/A, but I still think we should err more on the side of S for such a prolific Pokemon.
Just popping in, but why is Illumise B-Rank? It is pretty much a Volbeat without Tail Glow, which makes it seem a LOT worse. Is there something it can do that I'm missing that is better than what Volbeat can do?
I thought we agreed it would be D-rank last night, which is where I put it on the piratepad we were using. Volbeat is B because it gets all the cool Prankster moves and then can pass Tail Glow on top of it. Illumise performs roughly the same as a priority weather mon but doesn't have that extra role, since priority Wish is kinda meh from a mon with such low HP.
Nominating Omanyte for D-Rank. It, along with Dwebble (and Pineco which doesn't have an analysis) are the only NU Pokemon with Spikes AND Stealth Rock, giving it a niche. It has a decent 90 SpA, and it can burn physical attackers with Scald. (It can run Toxic Spikes, but why bother when Scolipede's running amok?) HP Rock provides STAB and coverage that KOs the birds, while Toxic can stall Misdreavus. It can also go offensive, with Surf, Hydro Pump, and Ice Beam, taking out Serperior, Charizard, Golem, Golurk, Piloswine, and Regirock. It suffers from poor speed and SDef and a lack of recovery, which is why I don't think it should get higher than D-Rank.
Omanyte is about the 6th or 7th best Spiker in the tier, and I wouldn't use it over any listed Pokemon that gets Spikes. It's absolutely horrendous and is 100% E-rank.
I'm just going to suggest that people stick to discussing Pokemon that are currently starred in the OP, since those are the ones that probably need the most discussion. Bring up crapmons later.
Edit: Marowak should stay C-rank, it's slow as fuck and doesn't get really any opportunities to set up. It's also weak to the 3 best attacking types in NU right now (Water, Grass, Ice). It's really strong but needs a fuckton of support, like Gigalith or Rampardos.
