Don't get me wrong, I'm not trying to claim my way is the only or even the best way! A thousand debates have been had over the "correct" Cosmere reading order, and I personally think there is basically no "wrong" order.

I've just found that the people I know who started with Mistborn, often struggled to get into Elantris and/or Warbreaker. I don't think it's unfair to say that they are not as breezy a read as Mistborn. And that telling them "it's a shared universe! You just gotta read these two other 600-page books before that starts mattering" is kind of a hard sell.
