damn this is so interesting. Its so amazing stuff get out after all these years. I like the idea that the male dwarf could actually be a monster. Also I dont think the guy has the female wizard figure. And based on Toco's research there is also a Centaur figure for the WQP. So based on the fact that each expansion would get 5 minis each id go:
Wizard Pack: Female Wizard, Minotaur, Spider, Centaur, Sabertooth
Dwarf Pack: Male/Female Dwarf, Rock Gollum, Dragon, Rhino, Skaven
The ones im certain of are Minotaur, Spider and Centaur go in the Wizard pack, cause it was based in greek mythology. Even though Skaven seems fitting with the others it has nothing to do with greek mythology so Ig they go to the Dwarf. Sabertooth seems more fitting. Im greek by the way so u can trust me on this.
Also Im pretty sure the Dragon goes to the Dwarf quest pack cause u can notice in the female dwarf figure that there is a dragon symbol on her shield.
The thing is there is a total of 11 figures considering this dude showed us 9 + female wizard + Centaur. Im not sure which one would be left out, my guess would either be Centaur since we have no figure of his, BUT he is 100% greek mythology material which makes him perfect for the WQP, or the male dwarf, who seems kinda unnecessary unless he is a villain.
Just throwing my two cents in
