We have Dunkmaster Darius 7-C Calc.
We have Amumu 7-B calc
We have Illaoi 6-C Calc
There is no scale for Amumu, but maybe there is scale for Illaoi.
Most characters are weaker than an elephant in armor. We know this from the elephant card in Noxus. So unless there are feats that prove otherwise, I think most Noxian, Demacian, Ionian and Freljord characters should have physical APs at Tier 9.
Let me even write the CRT I am thinking of making here so we can discuss it.
Freljord
Ashe can freeze the entire body of her opponents. According to this
calc in the References for Common Feats section, this is feat 9-A. Tryndamere should be at least as strong as Ashe. He should be able to help her in battles. Tryndamere can fight yetis and Willump is a yeti so Nunu and Willump should also be upgraded. Gragas is also in Ashe's unit and fought them when he first joined. So if headbutting counts as AP, he can be rated as 9-A. If not, we can rank him as Unknown.
Braum is also in Ashe's unit so he can be scaled to 9-A. The LoR loading screen says Braum fell and split a mountain in two. I assume he did this with his shield. His shield could be 7-B. I don't think this is an exaggerated rating since Ornn made this shield.
Sejuani should be comparable to Ashe since she is in competition with her. Sejuani can freeze a person's entire body anyway. She can take the same calc and get 9-A anyway. Olaf is already a scale to Sejuani, as stated in her profile.
Void
A
calc made for the cinematic where Vel Koz destroys the forest. Void characters that should be comparable to Vel Koz: Kha Zix, Kog Maw, Cho Gath, Rek Sai. Kha 'Zix and Rengar scale. Gnar also rises because he scales with Rengar. These characters are 8-B
Maokai-Ivern
Maokai should be 9-A since he
creates forests. Ivern is also comparable to Maokai as stated in the profile
