You're partially right A: The Altaic language family, which includes Turkish, Korean, Japanese, and Mongolian. Although arguing that the Bantu are now the best represented is valid because BHG added them into RoN as a language group instead of as the individual tribes (ie. Zulu) Among the most poorly represented groups are the Indo-Europeans, but that's because there are so many Indo-European branches like Germanic, Slavic, Celtic, Latin, Hellenic, and Indo-Iranian, and all of those divide up even further. Another poorly represented group are the Sino-Tibetans (ie. Chinese). Not to mention there are lots of groups that are not even represented, such as the Austroasiatics or the Finno-Ugrics.
