That said I'm still sold more on the idea of Seekers / Keepers being based on lions / every other feline. Aside from the squick involved, the incest implied in Seeker societies would eventually lead to them all becoming sterile and the species dying out (not to mention ugly as sin). Just look at the Hapsburg dynasty to see what generations of inbreeding produces.
(Again, "miqo'te have more girls than boys" is probably just a Doylist excuse as for why there were no male miqo'te in 1.x, just like "Hrothgar produce almost no females, so the ones that are born are always secreted away and kept safe" and "Male Viera exclusively live reclusive lives as forest protectors." Lore tends to take a backseat to mechanics, not the other way around.)
