Sandersons prose isn't bad, just different, from what I can see, and, as you note, Jordan wasn't always the paragon of perfection himself. Sanderson still seems like a pretty good writer, so as long as he gets all the details the way Jordan plotted them and isn't flat out clumsy with his prose I don't think it's fair to fault him for not being Jordan. I mean, would you rather the story never got told? I won't say Jordans prose was NEVER clumsy, but there were a few times when, shall we say, a mouse could starve on the difference. We could analyze the difference, but the candle probably isn't worth the wick. Also, you can't roller skate in a buffalo herd.
