Yeah, they probably do, but here’s the thing. Brandon did something in TFE where Kelsier would avoid thinking about his plan. It worked! And if it is about dragons, it doesn’t need to have a dragon main character. And if it is one, it doesn’t have to be the leader of the big corporations. I doubt that all of the dragons are like Xisis and know all the things.
And even if they do, why would they need to consider it in context of whatever story they are in?
