Another good example of his weakness in this department is how many scenes he needs to write for the little plot development/character progression he must cover.

Jordan had what.. 2 Gawyn POVs in the whole series? And about what...20 scenes in which he appears? Sanderson had a ton of Gawyn chapters, completely useless except to him, because of his own admission he didn't "get" Gawyn, so we were given his "walk through" of trying to make sense of the character. All material which should have been considered "preparatory" and end up in the thrash can once he did "get" the character and was ready to move on.

He does that too in his own novels, a lot. It's very curious that writers from the "multi-tasking" and "fast-paced with lots of ellipses" generation used to TV/movies language very often suffer from this weakness, and seem condemned to a step-by-step pedestrian progression in their storytelling. As for abuses of bland descriptions, that seems to be a flaw inherited from trying to make things "cinematic" rather than literary.

Brandon has fairly little instinct for what needs to be told and what should be cut. That is linked in part with a weakness at handling inner thoughts of his characters, forcing him to have nearly everything happen "on screen" at length, when some things are worth only a brief allusion in later inner thoughts or dialogue.
