I'd say the Mayans and the Chinese. Mayan has little to to no info about a lot of the Gods and Goddesses (both in-game and not in-game). And the Chinese are a real pain. As much as I have the advantage of being Chinese, and can read Mandarin, it's no secret that the SMITE lores and depictions are not accurate. And that screws up a lot of things as well as the relationship with the other gods. And because of the inaccuracy, I find it really hard to put the SMITE's version of Chinese Gods and Goddesses into the comic/story. Because this is like a dishonor to my culture completely.
