Rhyperior going from B+ to B is something I agree with. His bulk is good on the physically defensive side & he can hit back nicely but he does have trouble with the casual fighting types like, Infernape & Lucario with sword's dance as well as mixed attackers like Mega Abomasnow. Rhyperior can tank on Mega Beedrill, Snorlax, Entei, etc. Rhyperior doesn't really tank that much of the meta nor is it too great of stealth rocker, a tank, & it's speed is lack luster. Rhyperior should probably go down to B- even.
Forretress should stay in A in my opinion. I've seen a lot of experienced players do some flexible plays with this & talk about some flexible plays with this. Like, gyro balling Espeon, putting pressure on other hazard setters with rapid spin, etc. Slow volt switching is pretty decent too.
Goodra, not much to say except that I think it is a good tank on the special side.
