I would certainly agree with you on Chien-Pao but I'm not so sure about Gouging Fire and I think it has more counters then you say it has.Post about the two biggest issues in AAA, from my perspective!
So since I am done laddering for the foreseeable future I want to address the 2 elements within the metagame that I personally find egregious in nature and need to be addressed in some form.
Gouging Fire is frankly busted, and honestly entirely quick ban worthy. This is a Pokemon whose only real good answers are Well Baked Body Corviknight / Skarmory and the former is forced to run Iron Defense if it doesn't get the boost and the Gouging has Dragon Claw/Outrage as it can feasibly boost to infinity and then brute force through it. There are 2 common sets with one anti-meta set, the common ones being Magic Guard with Flare Blitz / EQ or Dragon Claw / Dragon Dance / Morning Sun or Desolate Land with Flare Blitz or Heat Crash / EQ or Dragon Claw or Dragon Tail / Dragon Dance or Dragon Tail / Morning Sun. Both of these versions can be built for speed or bulk (this ignores the fact that Gouging is like Great Tusk with usuable Special Defense even without bulk investment). The anti-meta set is simply Mold Breaker which allows it to bypass answers more readily whilst sacrificing power and longevity.
Gouging Fire is just flat out broken though, practically no answers and the ability to easily sweep with great overall bulk means you have a little leeway in regards to answering it's power.
The other Pokemon, Chien-Pao is less broken then Gouging Fire but I think it is even more unhealthy in nature rather then just straight up busted. Reason? Simple, Chien-Pao despite facing common answers in Corviknight is able to actually muscle by them through Flinch hax. This is ignoring it's blatant power and great offensive typing. This thing has remained in the metagame for a long time despite it's contentious nature and I think it's about time it received a suspect in order for the community to decide as the council is clearly too divided or at least was in the past. My change of opinion regarding Chien-Pao came as a result of a battle in which the opposing Chien-Pao broke through a defensive Primarina AND Corviknight through simple flinches, this isn't healthy sadly, if it weren't for Icicile crash this mon would probably be fine but the fact that it isn't effected by Fluffy just makes it so much worse.
TLDR; Suspect Chien-Pao, Quick Ban Gouging Fire!
First off, theres WBB Corv which just totally destroys Gouging Fire. I've also been seeing a rise in Hippodown being both Unaware and Intimidate variants. Primordial Sea Archaludon is more of a check than a counter, but it can work somewhat well against it. Deoxys-D is also fairly decent against it. I think both need suspects but I don't think Gouging Fire should be quickbanned. Then again, you are #1 on the ladder so idk lol.
