Reading orders could also be designed to make sure that people are introduced to Cosmere in a way that makes them hungry for more. For example, I saw someone on a board who had struggled massively with WoK because they thought it was just GoT with over the top world building and a Gary Stu central character. Now, WoK can certainly appear that way at first, but people who are familiar with the Cosmere know that all this world building makes sense somewhere and somehow, and people who are familiar with Brandon's work know that he's very adept at taking a cliche and inverting it all of a sudden. Not to mention the slow burn, which leads up to the Sanderson Avalanche. For such readers, Warbreaker would be a good start (Elantris might be a bit too cliched), whereas people who like intricate world building, but need to experience an Avalanche to be persuaded, would do best starting with Elantris.
