Thank you for your patience. Last week, the VR team voted on a new VR slate which manually ranks each Pokemon in each type. The updated VR will be placed in the OP, but here's the highlights of the new VR shifts.
Bug

Yanmega C->B
Choice Specs Tinted Lens Air Slash op

Frosmoth A-> B
Articuno + Empoleon usage hurts Frosmoth's viability.

Galvantula B->C
Araquanid is the most used Sticky Webs user, no HP Ice makes it not quite enough in the Flying MU, Water MU is a bit harsh due to Rain / non-Rain having answers to this guy.

Slither Wing B->C
Role compression is great, but just running Heracross + Lokix individually seems to gain more results
Dark

Sableye B->A
Mandibuzz hype might be slightly overstated, so Sableye was unjustifiably dropped in earlier slates. Being a spinblocker + general annoyer is still good.

Moltres-Galar B->C
Hard to find setup opportunities + compounds weakness with Mandibuzz/Screens Dark being niche at worst.
Dragon

Goodra-Hisui A->S
With no more Gouging Fire, Hisui Goodra is now a must to avoid getting eviscerated by Ice Beam or Moonblasts.

Roaring Moon B->A
Latios being the more common pick means that Roaring Moon gets the Choice Scarf (over Latias) in most teams.

Hydreigon C->B
Killing Steel has never been so nice! Also is a Dark resist that is able to deal with Hisuian Samurott is nice for the type.
Electric

Pawmot C->B
Speed + Bolt Beam Grass coverage is great. Mach Punch and Revival Blessing are also nice to have.

Rotom-Wash S->A
Suggested by
Heatranator specifically, but well Rotom-W doesn't seem to be of much use nowadays especially after Gougergone.
Fairy

Primarina A->B
Gougergone, and while Primarina's typing is broken in mus such as Flying and Steel, Azumarill with Nuzzle support can achieve more and have a broader matchup spread than Primarina at times.
Fire

Torkoal B->C
Ninetales is really just that good.
Flying

Landorus A->B

Landorus-Therian A->B
Votes between these two mons are mainly split, likely due to the VR team's preference on one or the other. Both are still doing their role as Choice Scarf user usually, but with Gougergone, there's less incentive to be proactive when you can wall off lots of cores with whichever 6 mons you choose in this type.

Moltres-Galar B->C
Cant use Moltres-Kanto with Goltres, and Dark resists + Hisuian Goodra is pretty annoying.
Ghost

Ceruledge S->A
Became less mandatory with people getting annoyed on how much Cerul needs to be babied (i.e. having Brambleghast) to function well.

Pecharunt B->A
Pivot sets to get Flutter Mane in is kinda great. It also beats Gliscor if you wanted to use an NP set, but you dont need to go that far.
Grass

Hydrapple A->B
Less needed nowadays with Gougergone, and it was too slow to begin with.

Lilligant-Hisui A->B
Meowscarada getting Triple Axel + Breloom being enough for Fighting STAB + Missing with Hustle is just sad sometimes
Ground

Landorus-Therian B->C

Sandy Shocks B->C
Use Landorus

Ursaluna B->C
Ghost immunity isn't that needed, Sandless builds often go without it.
Ice

Cetitan B->A

Mamoswine B->A

Weavile B->A
Decoupled the core mons in Ice from B rank, I think "no A Ranks" was just a problem in computation, not that the VR team thought Ice really had no A mons.
Normal

Porygon2 B->A
Bolt-Beam coverage is great, and it can take a lot of punishment or use Substitute to be annoying to non-Cuno Flying.

Indeedee C->B
Choice Scarf sets keep it better than the other C rank mon, so it rose.

Braviary A->B
Normal has an odd 5-slot syndrome, and Brav is oftentimes dropped if the team wants to become more creative. Eq spam can also be handled well enough by Porygon2.
Poison

Toxapex B->A
Fire Resist + Tspikes + Whatever item's annoying

Iron Moth A->B
Being SR weak on a mon thats supposed to come in a lot of times to punch holes isn't that great.

Glimmora B->C

Clodsire B->C
Entry hazards in Poison isn't as mandatory, and with Poison needing 5 mons to function, its hard to fit these over potentially more impactful team mates.
Psychic

Hatterene A->S
Psychic currently has difficulty in entry hazard stack due to not having viable defoggers/rapid spinners

Armarouge C->B
Steelbreaking + Meteor Beam strats are quite nice for Psychic

Metagross A->B
Jirachi / Necrozma is slowly coming for Metagross' job, competing for a spot as a Steel type / entry hazard setter
Rock

Glimmora A->S
Toxic Debris helps Rock lots on whatever it wants to do, considering the "lack" of removal in mono.

Tyranitar B->A
Sand is great for allowing team mates like Gargnacl to outlast opposing teams + Knock off

Iron Boulder S->A

Arcanine-Hisui S->A
While these two are still great, they aren't as "key" mons for Rock to function as the current S rankers.

Minior B->C
Shell Smash sweepers aren't so hot right now.
Steel

Bisharp B->C

Iron Crown B->C
Setup Sweepers are pretty underwhelming in the current iterations of Steel. Specs Iron Crown is neat, but its not fast enough.
Water

Rotom-Wash C->B
Rainless Water's answer to Earthquakes and the ability to muscle through Articuno is really great these days

Keldeo A->B
Urshifu-R is more splashable, and Dark/Steel isn't as oppressive to warrant Vacuum Wave.

Primarina A->B
Manaphy is easier to slot in as a special setup sweeper
This is all for this rank update, op is already updated. We hope to hear feedback from these changes!
