Starting in Season 2, "Shadow and Bone" has begun introducing a map that shows where the characters are during scene transitions, and fans have been loving it. Being that the YA series only began in 2012, while Robert Jordan's "The Wheel of Time" has been around since 1990, the background lore and extra material for Jordan's series is more than two decades ahead of its counterpart.
This means that Prime Video has that much more to draw from for the many maps and locations of "The Wheel of Time." Furthermore, if you consider how vast and expansive the world that Jordan created is, especially as the series goes on and characters split on their own paths, it's easy to see how adding a map would help to ground viewers in this world.
Finally, if "Shadow and Bone" can make this type of change in Season 2, there's no reason why "The Wheel of Time" doing the same in its own sophomore effort would suddenly ruffle viewers' feathers. On the contrary, they would almost certainly love the new addition just as much as viewers do on "Shadow and Bone."
