It's been a day and I'm liking the bans so far and I'd like to share my thoughts. Wall of text ahead.
I feel like the tipping point for Shifu was Punching Globe, it amped and made Surging-strikes very spammable.
Banded Tera or SD surging-strikes on a 130 base attack mon 1HKO stuff though resist. Globe further grants power, even it's only a 10%, it's still massive for such high damage output plus avoiding contact. In gen 8 offensive Shifu had to chose between band or safety from contact chip, now with Punching globe and Tera it gets both.
Shifu's 97 base speed sits in a comfortable speed tier, it's faster than a lot of meta key Pokemon like Tusk, Dengo, Rotom, Lando, Glimmora and H-Samutt forcing out switch ins. That's huge for a Pokemon that's fat, hard hitting and is even more busted in rain.
This Pokemon gained too many tools this gen and now is closer to his busted brother. Definitely too much for OU.
Volc is cheap, specially the fat phys def set. Facing this mon always made me feel like walking on thin ice because it could come back at any point and reverse sweep. Every team I used needed a double check for Volc's possible teras, because they counter it's hardest counters.
Tera Grass beats Garg, Dozo, Ting Lu, Azumarill.
Tera Ground beats or overwhelms Dirge, Heatran, G-king, Pex.
These two teras are big considering Volc can neuter physical attackers with wisp or flame body, while quiver dance can fully wall special attackers and also there's no use for hazards since Volc always runs boots and now is harder to remove Heavy Duty Boots with lower knock off distribution. Most priority fail to revenge kill, even tera water Azu aqua jet fails to OHKO HP Volc from full.
When it comes to checking stuff I don't see much loss from Shifu. Water and fighting types were already prevalent because of Gambit and Tusk, however Volc's Fire/Bug combo is unique, the closest thing to replace it is probably fire/flying (x4 weak to rock, x2 weak to water, resist grass, steel, fairy, fighting, u-turn x4, they differ on electric, flying and ground interactions though) however Moltres doesn't have the versatility to replace Volc's offensive niche.
Now that being said, I read somewhere in the thread we were allowed to vent our frustrations here. So I kinda want to hit on both sides.
First, I don't think the player base is entirely reliable at pointing which Pokemon are busted or not, at some point Espathra fell to UU, Baxcalibur fell to UU, Shed Tail Orthworm was UU, Dondozo didn't have much use during Palafin's reign of terror, Annihilape and Chi-Yu stayed in the dark way longer than they should have, Banded Pao didn't have much use until very very late pre-home. so It can take quite a long time for the player base to pick up how busted some Pokemon can be. Even water shifu as busted it is now, it didn't have much uproar from the player base until the ban.
People don't realize (or don't want to admit) how busted is Volcarona, it wins almost every neutral match, it can win against several physical attackers just by making contact, it can win against many special attackers after only one Quiver Dance. Volcarona covers so many bases: physical mons, special mons, doesn't care about hazards with low Knock distribution, it can overwhelm just by spamming Fiery Dance getting free +1 SpA, it has high min-maxed base stats of 100 Speed 105 SpDef 135 SpA. It has speed, it has bulk, it has offense, it has status, it has a single offensive and defensive set-up move and immense coverage, then you add Tera and you have a near perfect Pokemon. So I really find hard to disagree with the ban and I find ever harder to make arguments as to why Volcarona is a balanced Pokemon.
Regarding council. Feel free to correct me if I'm wrong or if you disagree.
I don't think council have done a good job with gen 9 since the start. IMO the first big mistake was the Tera suspect. It's shouldn't have been a super-majority vote. It should have been a simple-majority Tera-on-team-preview suspect at first, and from there evaluate a proper Tera ban suspect. I say this because before gen 9 there was already a lot of discomfort with the state of gen 8 OU, ending in a boring a overly defensive regenerator spam meta, the "ban tera" premise scared people and made them go into gen 9 in a full pro-offensive pro-tera pro-fun anti-ban mindset, resulting in the whole suspect in no action.
The second mistake was letting Zamazenta-Crown, Hero, Magearna and Pao into OU, these Pokemon are beyond busted on their own right. They were released on the premise of power creep, but the problem is these pokemon as well gained the all these new tools. +1 STAB defensive Body Press Zamazenta is no joke, it's extreme fast in a slower smaller meta and can make unbreakable subs while avoiding passive play. Magearna is not a balanced Pokemon and will never be a balanced Pokemon, Magearna and the word balanced are mutually exclusive. For Pao not even fully physdef Dondozo (the strongest OU viable physical wall) can't switch on 2 Tera banded Crunch. These Pokemon are mistakes and should never leave ubers again, and them getting no-ban on the radar vote was illogical.
As much as I support these two new quick bans, they contradict the idea of using surveys as feedback, it makes players surveys feel useless, and they felt rushed and pressured from the previous radar outcome.
IMO Zama-hero needs to be quick banned, like right now (based on survey), and then there should be a simple 51% majority tera on team-preview suspect, that would at least alleviate all the Tera debate going on right now. That's my opinion.
being the best hazard control mon in the tier it seems like. I wonder who would be the best Hazard setters of the tier going forward.
. I wonder if 
would be a nice option as well.
and 
to be among the best setters?
and 
take this mantle?
niche tbh tbh
