The thing is it will never hinder the ability to KO/2KO anything it wouldn't already.It’s gone too far already. I saw a team with a Marowak at Level 94. One wonders at what point it’ll start hindering their ability to net the KOs they need to get.
There's not any important rolls it misses out on at even lvl 90 since it OHKOs most stuff by such a large margin; with 512 attack even at 10 levels lower.
Also Poltergeist+Flare Blitz is just so incredibly strong and useful it's insane.
In OU some variants don't even run max attack since 150+ adamant still 2HKOs defensive Kommo-o after rocks and it needs way more Spdef bulk.
