This bit is nonsense. Much of the list is completely unviable in OU, or so niche as to be ignorable - and that's the point, that defog distribution is terrible and it's not primarily about Gholdengo - but there's a full half-dozen mons there that are viable OU choices, and five of them can reasonably run Defog.
Those six, along with their current ratings on the VR:
Corviknight : B+
Frosmoth : C
Hawlucha : B-
Lilligant-H : B
Scizor : B
Talonflame : C
I also cited Maushold as a removal option, who is ranked at C+.
Your first list had 15 mons and now we're down to 6, I'd say over half could be considered "most" as in "most of these are unmons" but we can break it down further.
Y'know what C+ tier in SV VR means? Mostly RU mons, literally. 2/6 you listed are below C+
The SV meta is mostly B+ and above, which none of the ones you listed are, besides Corv.
There's a reason none of the sample teams have mons below B+
Let's set aside Corv since it's B+ and a viable fogger. You say the other 5 mons are viable OU choices- we can disagree. I'd say they were the mons I was talking about when I said "with few that have an actual niche." RU mons are more niche than "viable OU choices"...
A niche mon is a mon that is often not an optimal pick. They have a high skill ceiling and should only be put on a team by someone who knows what they are doing and can build the support these mons need to even perform their niche role; pretty sure Frost and Talon meet that criteria dude. Where you lose me completely is when you say they can all reasonably run defog. They can't.
So, not sure how you think what I said is nonsense. You had a list of mons, over half of them weren't ranked or below C and the remaining ones are niche picks, like I said.
The removal ranking is this:
- Cinder
- Mouse
- Tusk
- Corv
- Treads
- Quack
This list is heavily factored by Gold. Corv would be #1 without it around. Notice how 1 and 2 spots are mons that aren't stopped by Gold. Tusk and Treads need to watch out for scarf, balloon, tera- basically not a free spin whatsoever with Gold around.
However, if anyone wanted to put Tusk at #2 and Mouse #3 then I wouldn't argue. Anyway.
The interaction between Gold and Corv is a huge reason why hazards are such a problem, less than the defog distribution.
The distribution doesn't help our situation, but Corv comes in and fogs for free vs like 70% of the meta without Gold. Hell, with Tera, Corv fog could technically only be stopped by Taunt, and none of those Taunt mons want to eat a BB, Iron, or get U-Turned on.
If mons could access egg moves and whatnot like in SS then we would have a totally different meta. You can't really say it's a distribution problem when that implies the mons also get Toxic and Scald back if they get Defog back.. Again, distribution doesn't help but in the meta we currently have, with moves that GF wanted these mons to have, the fact that our premier fogger can't do its job is the biggest factor in regards to hazard stack meta.
