Don't forget Starmie, who's actually really solid now.
Anyway I've definitely been convinced that thanks to Lopunny + Gallade, Terrakion, Heracross, and Medicham are significantly worse. Medicham was hit the worst, since it really is just a niche variation of Gallade. It isn't bad by any means, but what does it have over Gallade? I guess it 2hkos unaware clefable (gallade can too w/ poison jab...), but that's certainly not enough to keep it A. In my head, I see Medicham
Salamence, so if Pinsir really does belong in
B, Medicham does as well. Heracross was hit seemingly less hard, since neither Lop nor Gallade directly outclasses it. However, in this current metagame, why would I use a mon with 185 and 75 speed when I could use a mon with 165 attack and 110 Speed OR a mon with 136 attack and 135 Speed? Fighting/Rock/Bug Coverage isn't anything special, since stuff like Doublade 100% walls it. Lopunny doesn't have to worry about this, since with 2 moves it gets unresisted coverage. It is significantly weaker, but atm a) stall is based around Mega Sableye, something Lopunny easily kills, and b) offense is really popular, and Lopunny fairs much better against it thanks to outspeeding everything except Sceptile, Beedrill, Dactyl, and Zam. Then you throw SD Gallade into the mix, and reasons for using Hera further diminish. I'm feeling
B+ for it, but I'm not sure, since I'd rather use most stuff over it. Terrakion still has Stealth Rock to boast, as well as the ability to a) hold items, and b) be used with a mega, so it was definitely hit the least hard. However, if you were using it for anything other than a SR Sash lead, it's basically a worse Lopunny/Gallade. This
probably fits best in
A-, but then again, Manaphy, Jirachi, and Politoed are all a lot better than it.
