Ok, jokes aside, time to show your cards
Here is all main attemts above:
Warning, a lot of pics
First of all, we know, that initial Skyknight suggestion also contain 3 correct names and ther is not dreadblade. Also Zealot revealed. and +solder is not slayer.
Next, check 0 matches.
MoldyPoptarts: Demolish is not Hellion, NB is not Slayer, Necro is not Reaver.
Skyknight #5: Occultist is not Desecrator, Shaman is not Thane.
MoldyPoptarts #2: Soldier is not Gladiator, Occultist is not Harbinger.
MoldyPoptarts #3: Demolitionist is not Dragoon, Shaman i not Wilding, Inquisitor is not Custodian, Necro is not Blood knight
Gumshoe: Soldier is not Juggernaut
Skyknight #6: Shaman is not Evoker
Denismashutikov: And my last, Occultist is not Beastmaster, Necro (obviously) is not Bone Charmer
Now Lets see 1 matches.
Thane is met 3 times, it was seen far before, but it almost 0 chances there is not truth. Otherwise a lot of combos possible and we at dead end.
2nd possible candidate is Reaver. It matches 2 times, but alternatives are doubtful.
And with this two suggestion we get next sudoku:
My last list exclude Occultist as Beastmaster, and there is only one option in Ceno attempt left: Evoker.
All reasoning above correlates with the initial condition: 3 correct names: Thane, Reaver and Evoker. One of them correct (Reaver).
So we get:
+Soldier: Thane
+Nightblade: Reaver
+Arcanist: Evoker
+Oathkeeper: Zealot
