I still don't see that happening. Scrafty takes out most of the in-game bosses without help and without hassle. The only time my Scrafty ever died was against Flying types, which is a problem for pretty much all Fighting types.
Why are you using Payback when Crunch is the more reliable, superior option? Also Metagross is in Challenge mode, not Regular mode.
90 offense is just fine for in-game. Not to mention
it's fucking weak without moxie
So I suppose Azumarill, whom we argued about earlier should automatically be thrown down to Mid because it's a complete joke without Huge Power? Magnezone without Sturdy doesn't nearly have as much usability because you can't switch it in on nearly as many foes for OHKOs.
I used Scrafty over Magnezone a lot simply because it was better in the long run, and almost always killed things with ease. The only things it had trouble against were Flying types (a given, being a Fighting type, and I fail to see how Hera would do any better). Once again, Scrafty has no trouble with most of the trainers in the game. Isn't this about how the Pokemon performs in the game, not if it's outclassed by something else?
Also, Poison Gas is a bit overrated. It's got accuracy issues, which I'm no fan of.
