This is beside the point but come to thing of it, the rational that pretenders with some advantage that are only available for some of the nations should be disqualified might apply to some more human pretenders.
For example the alchemist. Alchemy by itself is a clear advantage and he's only available to a few nations.
I guess it has to do with wether the idea behind having human pretenders is thematic or for balancing. Because for perfect balancing we might as well have all taken the same pretender. but that's not fun imo.
The game is fun and for sure I'd like to continue playing. I take it that this advantage isn't considered as a problem by fellow players, so I'll happily continue
