Agree on Roaring Moon and Gouging Fire, especially Roaring Moon. Disagree on Raging Bolt at the moment.
I know Bolt has gotten a lot of attention lately. It's quite slow, doesn't speed boost much with Dragon Dance like Gouging can, and has a priority move that nearly every team has a common immunity to on it. It can be hard to switch into. But I feel it basically acts as a Wallbreaker with a priority move. And even most opposing priority mons will out priority it because of the Speed tier. The Dragon typing does resist Grassy Glide and Aqua Jet, but likely not if it Teras to live your team's ground type. Although I guess something like Tera grass is maybe an option, it opens you up to other weaknesses. Raging Bolt is also kind of a Tera hog. If it Tera's to live a hit, that means its teammates can't utilize it. This may or may not be enough value out of the Tera to secure the win. But often it isn't since Bolt isn't really a sweeper.
It is splashable on a lot of playstyles and I think a vital glue mon for the current meta. With Arch gone, rain should be more manageable but still good. With both Arch and Bolt gone, rain will be back in the pits. Even though Bolt is far from exclusive to rain, I do think rain should be allowed some bulky glue mons. I would also like to see Gouging Fire go before we see another rain nerf. Sun is likely to be too strong over rain in the short term because of the Arch nerf to rain and Gouging Fire destroying every defensive core like a physical Chi Yu. Meanwhile, Bolt is good on both weather styles. But a Bolt ban would be far more detrimental to rain at this point. I would argue to take away the Sun exclusive mon first and see where we are at.
I also believe a Bolt ban would be bad for Balance since it is such a good glue mon. There are a lot of potential threats with speed that can tear apart a balance core too easily. The threat of a Thunderclap mitigates this somewhat. In gen 9, you basically can't run a viable non-stall team with no priority moves. There are simply too many threats to account for everything. And you can't run a balance core or bulky offense with no viable bulky cores.
There has been a lot said about Kingambit and whether or not that should be banned. Raging Bolt is kinda like a special Gambit, except it only gets one free special attack boost as opposed to Gambit's Supreme Overloard, which adds up over the game and is valid on every switch in. If you force Raging Bolt out, the Protosynthesis Boost is over except on Sun. The difference in typing on the priority moves is also huge. Not only does nearly every team run an electric immunity as a matter of course, but the Electric typing in general is way easier to resist than Dark type STAB. I would argue that if we are going to ban Raging Bolt, we should look at Kingambit again first. And if I had to choose only one to keep in the tier, I would keep Bolt in the tier. Not Gambit. Folks can disagree with that, but I really think Bolt is easier to deal with of the two.
Speaking of Dark type STAB being very hard to switch into, Roaring Moon has already been rightfully banned before. It has a way better speed tier than the other mentioned mons and Dragon Dance on it is just silly. The only ways to really counter it are unaware mons and priority, but booster attack still hits Unaware mons and the priority can be potentially countered by Tera if a certain move gets too common. However, Tera Flying is by far Roaring Moon's most common set. Raging Bolt counters this with Thunderclap. Yes, they could just not Tera. But if they don't Tera, they are easier to deal with. Keeping Bolt in the back can keep a lot of potential threats at bay. Now I'm not saying we should keep Bolt because broken checks broken or anything. Like Moon should just flat be banned regardless. However, there are a lot of threats that Thunderclap is just plain nice insurance for. I would argue that this destresses the teambuilder more than Bolt itself stresses the teambuilder.
