Hana
Olivier: 8-A (Scales to Roland)
Mirinae, Harold: At least 8-B, likely 8-A (Hana grade 1s at the very end of the game, keypages made for reverb)
Index
Yan: 8-B as a messenger, 8-A distorted (messengers=capos=grade 1s and distorted yan is same rung as Iori)
Proxies: At least 8-B, likely 8-A (Argalia notes that they could hurt him, even if he'd win. Considered way too strong for the capos to handle)
Proselytes: Not sure.
Thumb
Kalo: At least 8-B, likely 8-A (Sottocapo=Proxy, also gold keypage)
Capos: 8-B (Equivalent to grade 1s, those specific 3 were noted as "competent capos" by Hana)
Soldato: Not sure.
Color Fixers
Iori: 8-A (Color Fixer)
Gebura: 8-A (Color Fixer)
Argalia: 8-A (Color Fixer)
Gear worshippers: Not sure, probably pretty variable.
Liu
Xiao: At least 8-B, likely 8-A, 8-A with EGO, see her page.
Miris: I don't even know, he's randomly really jacked in his last fight despite being close to dying, need a way to explain that outside of game mechanics
Chun: 8-B (Fighting alongside and against 8-Bs, Grade 2 fixer)
Lowell: 8-B (Grade 1 fixer, though I could buy an argument for him to be a splitter based off him being a section 2 director and gold keypage, need to hash this out)
Cecil: 8-B (Grade 2 fixer)
Mei: 8-B (Fights 8-Bs)
R Corp.
Captains: At least 8-B, likely 8-A (See Myo's profile, Nikolai's Disposal would be 8-A flat)
Generic soldiers: 8-B (Based on their more concrete feats, as we already know they can punch above their weight in groups. Could buy an argument for Rhinos to default to splitters based on them being way too destructive for Lobotomy Corp, but eh.)
Cane Office
All 3 of them as 8-Bs (Grade 1s and 2s, no real feat of punching up at an 8-A and instead we get the opposite [though tbf it's Pluto], Nemo is a gold keypage but personally not super sold on the splitter for him atm)
General invitations at a flat 8-B unless we get more context for any of them in Limbus.
People may disagree with aspects of this and that's fine, it's not set in stone or anything. Also note that I wasn't planning to have all the Reverb guys as flat 8-A.
Reverb
8-As: Argalia (Color fixer), Elena (Fought 2 color fixers, fights the Binah floor), Zombie Vermillion Cross (Zombie Color Fixer), Pluto's barriers (Traps Iori, invincible), Tanya (Explicitly as strong as Gebura), Greta (She's 1/8 of a Star of the City level threat before distorting, doesn't use allies, has an instakill), merged Phillip (Blazing Strike's compared to Great Split Vertical even for half ego, when he's merged he doesn't use allies)
At least 8-B, likely 8-A: Pluto's AP (Very hax reliant, summons), Puppetman (summons), Oswald (summons), Bremen (summons), Eileen (summons), Non merged Philip (there's like 5 of him, the smaller angels are obviously weaker individually than the huge one)
