There is, but large majority of IH use AV in order to tank a hit from Flutter Mane and 1hko with Heavy Slam.There is still the ability booster who works like a Choice item without being locked ? (Few switch in VGC)
Plus it's a pokemon you tend to shuffle a lot (having access to both Fake out and Volt switch, and being victim of intimidate) so the one time booster energy doesnt work well (it's mainly used on Bundle instead and occasionally on Fluttermane)
The thing is, less threats = less things to prepare for. It's easier to teambuild when there are a limited amount of pokemon you have to account for.Personally speaking, I consider having a meta in a game like Pokemon so centralized that there are only 21 unique mons amongst the Top 10 teams is pretty damning in itself. This is, like, Leroy in Tekken 7 levels of saturation, and yet the culture with VGC seems to consider this acceptable.
Isn't one of the current issue of OU specifically the fact that you have so many threats to prepare for that it's a nightmare to cover everything ?
