Anywaysso uh the suspect is coming to an end so uh
Roaring Moon is unhealthy.
I do not want to see it back in the tier.
Why is Roaring moon unhealthy?
Roaring moon cannot be reliably checked. there is one set which will destroy your counter. You run Skarm? too bad this one had Darkinium Z. You run Clef? too bad this one had Steelium Z. You can get through it most of the time, but this is a pokémon even Dondozo cannot check all the time, Darkinium Z in sun Killing it after Meaningless chip and hazards. I do think that a pokémon that can destroy at least one of its counters at will is an unhealthy pokémon. I also think that it is harder than tolerable to revenge kill. Barely anything can revenge kill it behind screens, and it is a screens staple, or at least it is on the road to become one. If we craved HO so much as to unban it, the move was not to ban Tera and continue to spam HO.
Does it bring anything valuable to the tier?
Roaring moon brings a HO mon that's a Pain in the ass for KGB to Revenge kill, that makes it harder for val to choose what moves it runs on Specs and CM sets, with vacuum Wave being decent instead of whacky, and that encourages the use of suboptimal sets like Dazzling Gleam Terapagos (I have seen this, and it didn't even work). Sure, it brings one positive. Diversity in Sun teams' dragon Abuser, and a Yard switchin itself. But I think these attributes are Largely outclassed by the dangerousness and uncheckable-ness of this mon. take Volcarona, make it faster, make it hitharder, make it have Higher BP moves, and entirely remove its Weakness to Stealth rocks.
It's not unhealthy, it's not broken, and it's not even that good. It's being unbanned because it's not banworthy.
