What I find most interesting is that China and South Korea are consistently different from the International population, in particular they appear to be even more focused on picking the highest dps jobs within a role than international players are. E.g. Chinese and South Korean players are much more likely to play Paladin, White Mage, Summoner, (Black Mage to a lesser degree), Samurai and Machinist over other jobs within those roles. And likewise the opposite for international players who are more spread out across the jobs even though those 5 are still the clear favourites. The one weird outlier is Dark Knight in South Korea, so there's probably some cultural thing there that makes it super popular.
Oh and RDM is more popular than BLM in the international population. Huh.
