I agree with this. Mola without Pon still has to deal with Clodsire and Volcanion. The first one spams hazards and status, the second one is a good breaker that bypasses Mola unless it uses Mirror Coat. There are other decent Water immune Mons such as Poliwrath (Knock Off + Circle Throw + epic typing that checks every Dark Mon except Moon), Toxicroak (Rain Mon that has impressive movepool and interesting typing), Gastrodon (Clodsire but without the Poison moves and typing), Vaporeon (the Regenless Mola that has much better special bulk and offensive presence while invalidating Mola) or Tatsugiri (spinner than can also sweep with NP sometimes). Apart from that, there is also the general Mola passivity that lets many Mons to take advantage of it, you don,t have to run immunities to prevent it from doing its job.
Manaphy has an even worse case. Its RUBL. It not only is balanced and with almost no usage in OU, but its also balanced and almost no usage in UU. So, in the unlikely case it starts to look problematic (which won,t happen, cause OU has a lot of Grass types, Electric types, Kyurem, Water + coverage resists, special walls, strong and faster revenge killers, etc.) in OU, we just go to UU Tier, see what Mons are giving troubles to Manaphy there for it to have such low usage and chances are at least half of them will be viable in OU.
Waterpon is currently (at least for me) the most problematic OU Mon, more than Kyurem ever dreams to be. Hopefully the survey ends up reflecting that.
Mola can easily tech for Volcanion, esp if its an Offensive set, with Mirror Coat and blow it back. Mon is also getting worn down fast by hazards if it runs another set like specs. In fact, a good number of Volcanion's sets will be struggling to make Progress against Mola. In general, it will only beat Mola with the Fire Spin Taunt set, which is good, but a bit specific.
As for Clodsire, that mon is just too passive. You Wish with Mola and switch out for free. Admittingly, the hazards clod can set up can be annoying, but one of Mola's best partners, G-Weezing, can just Defog them away & Wisp clod for its trouble. Gliscor also completely destroys clodsire, which Mola will often end up being paired with, as do several other breakers that it will be paired with like Ursaluna and Great Tusk (you get Toxic'd but Mola Wishes to heavily alleviate the chip damage from that). Most of the time, Clodsire will struggle even making progress against a Mola team since they are filled with boots mons, though I suppose you could capitalize on this with Weavile or your own Gliscor. And let me just say, that Mola enables FAR more degenerate wallbreakers since it gives them recovery to complement their crazy bulk. Even with Waterpon around, dealing with some of these Mola comps is a nightmare, and I'd imagine it being banned would only make dealing with them worse.
As for manaphy, half the mons you listed are not checks. Grass-types lose to Ice Beam, Kyurem loses to Alluring Voice, Waters all lose to Energy Ball, and even other guys like Raging Bolt and Pex can lose to Tera Blast Tera Ground (which I've faced a few times). And lets not forget the cheap Acid Armor Stored Power sets that can also ignore status and toxic as well. Manaphy's higher item Versatility and wider array of Tera types make it nastier to deal with than Ogerpon-W IMO (for Balanced teams anyways) and its higher effectiveness in OU is attributed to the top mons (Lando-T, Tusk, Gliscor etc.) being food for it. All that said, I could see some of the guys that it struggles with in UU, like Lokix, Latios, Torn-T rising to combat it, but it has better partners in OU to deal with those foes like Raging Bolt, Corv or Ting-Lu. IMO this Pokemon hasn't so much as fallen off - rather it has just been under the radar, since its been very potent whenever I've used it (kinda like Garchomp which I think is similarly crazy still).
There may have been a time I wanted Waterpon banned (back after Arch was banned), but a lots changed since then. I've learned to sequence against the mon better (setting up hazards is key), put it into annoying 50/50s (getting it into more situations where its forced to click Power Whip so Corv / Skarm can deal chip to it with Rocky Helmet, clicking Ruination with Ting-Lu instead of immediately setting up hazards, etc.), running more speed Control mons like Dragapult and Zamazenta (which Ogerpon-W has to awkwardly sequence around), more soft checks like Raging Bolt on balance / bulky offense, alternative Tera-types on mons like Samurott-H or Ting-Lu (which are useful in other match-ups like against Iron Valiant), and I've gone from hating the mon to actually appreciating its presence in the tier given its utility with Encore, ability to actually threaten unbreakable mons like Ting-Lu and Alomomola (which IMO are FAR more cancerous than Ogerpon-W), while also possessing a clear, notable weakness in the Item / Tera lock, middling bulk, and mild 4MSS. If it was suspected, I probably wouldn't vote ban at this time.
