Firstly, I want to thank those who have reinvigorated some life into this forum again, and I apologize that I haven't been as much with work and the meta being mostly solved.
Second, with ban discussion hearing up again, I'd like to make a list and get community thoughts on what should and shouldn't be banned. If you have any suggestions for additions, feel free to tell me and I'll add them to the list.
Evasion abilities
Yanmega
Volcarona
Clefable
Kingambit
Kingdra (or rain as a whole)
Ursaring
Any potential clauses
The Yanmega issues is one that's mostly just recent, Volcarona falls under the same "Uber that's still in the meta" umbrella, Clef and Gambit have always been controversial and remain so, and Kingdra and Ursaring were more found out about being potentially broken and not just great after the meta. I will be responding to this message with my own votes on these things, and if we have enough people using the thread who want to share their thoughts and vote, we can have more clear options for what to do with the meta
Evasion abilities- Restrict if possible, ban if not. As much as I would love to run Cetitan teams, if there is no way to disable Snow Cloak/Sand Veil while keeping other abilities active, I do think that these abilities should be banned.
Yanmega- Ban. Initially, I disagreed with Inky and others who brought up the idea, but after seeing the calcs provided and their explanations, I understand the viewpoint more, and have been finding myself agreeing with them.
Volcarona- Ban. The big think making Volcarona a question mark for some is the increased viability of Unaware. Clodsire and Clefable are both in the big five, Dondozo is still great, and while used much less, Skeledirge and Quagsire are still used. However, Volcarona can stop most of these pokemon through a specific tera or sub sets, sometimes both. It's pool of counters is already limited, and when three out of five of the best options to stave it off only fit on very specific play styles and the other two can just lose to a new tera type or a Sub set, it does warp the meta around itself.
Clefable- Ban. Clefable has long proven to be a menace in the meta. Unlike gens 7 and 8 pokebilities, though, the only really problematic sets are Cosmic sets. However, I don't think banning Cosmic Power would be a good option as there are plenty of pokemon that aren't broken despite having Cosmic Power, mostly due to their abilities not preventing passive damage and making it to where you can't set up alongside them. Tera just boosts this monster even further beyond the point of brokenness
Kingambit- Ban. The addition of Defiant just makes this already questionable presence completely broken. Kingambit is already a very contentious pokemon, and random bits of RNG like a Shadow Ball SpDef drop from Dragapult or a Moonblast SpAtk drop from Clef more often than not lead to Gambit becoming completely uncounterable, and even uncheckable in many cases.
Rain- No ban. I believe rain is an issue with Arch and Kingdra, but Arch was just banned and I'm about to get to Kingdra. I don't think the entirety of rain is broken enough to be banned, or even that good if Kingdra is banned.
Kingdra- Ban. If Kingdra sets up a Focus Energy, there is no stopping it. Not even mons as bulky as Blissey or Clodsire are able to stand up to Kingdra if it gets the Focus Energy. 252+ SpA Sniper Tera Water Kingdra Weather Ball (100 BP Water) vs. 4 HP / 252+ SpD Blissey in Rain on a critical hit: 381-450 (58.4 - 69%) -- guaranteed 2HKO after Leftovers recovery
252+ SpA Sniper Tera Water Kingdra Flash Cannon vs. 248 HP / 252+ SpD Tera Fairy Clodsire on a critical hit: 252-297 (54.4 - 64.1%) -- guaranteed 2HKO
Ursaring- Ban. It took a lot of me using Ursaring and not just playing against it for me to feel this way. This thing warps so much of the meta around itself. Facade, Close Combat, and Crunch provide perfect neutral coverage on everything, and whether or not it's Trailblaze or Swords Dance is a mixup that isn't always easy to tell based on the rest of the team, which can easily lead to a sweep. With tera normal, Ursaring can 2HKO Dondozo with Facade, and with an SD boost, Ursaring 2HKOs Corviknight with CC. Rocky Helmet on these pokemon can help, yes, but teammates doing chip damage and using Knock Off is pretty easy to achieve over the course of a game. Nothing can stave off Ursaring more than twice per game if the Ursa player is smart with their play and. Helmet Corv is the closest there is to a counter with Pressure and the chip damage from the Helmet, but even that can get 2HKOd by +2 Crunch, not even requiring CC since you have to drop Leftovers. +2 252 Atk Guts Ursaring Crunch vs. 248 HP / 252+ Def Corviknight: 182-215 (45.6 - 53.8%) -- guaranteed 2HKO after Stealth Rock
+2 252 Atk Guts Tera Normal Ursaring Facade (140 BP) vs. 252 HP / 252+ Def Unaware Dondozo: 300-354 (59.5 - 70.2%) -- guaranteed 2HKO after Stealth Rock and Leftovers recovery
Those are my thoughts, hope to hear others
