>>24869904Volcarona has access to arguably the best boosting move in the game, and it's still held back because of the rock weakness, which is so crippling it basically gets one shot and that's it.
Dragonite has to worry about rocks breaking Multiscale.
Eviolite Scyther can be good, but that 4x weakness is a huge deal and means it can only come out in the very beginning before rocks go up, or the very end when rocks have been cleared. You're fighting 5v6 for the entire middle portion unless you can get a revenge kill and rocks still aren't up, and you can set up.
I'm not saying it's unworkable, but being 4x weak to rock is really bad.
