Fucking this. 100% the Seanchan, Seafolk, several of the costal nations. They didn't need to force diversity in a way that compromises the source material.  Also, I'm on book 7 too but.... like idk 8 or 9th read through...sorta. I'd reread it fit every release, so I've only read the final book once and books one through 6 or 7 a bunch lol Idk but I swear if there's an Aiel or Borderlands nation person that's fat I'm gonna be annoyed. I think the last major casting they need to announce for early series is Thom. Still no sight of him
