Along with No Preference when selecting role preferences, I think there should be a Prefers Hunter option and Prefers Monster Only. Because sometimes I’ll want to be Hunter but don’t really care which one but have to prefer one over the rest. But then I might end up taking a class that someone really wanted. Same when I want to play Monster. If I don’t get monster, I don’t mind which hunter I get. Let the other people get the role they want.
So pretty much, Hunter Preference = Any hunter then monster
And Monster Only Preference = Monster then any hunter
