It's funny that you should mention the Wheel of Time, because that reminds me of something else Robert Jordan tends to do.
Having just finished reading his Fallon trilogy, I noticed a startling similarity between it and the Wheel of Time series: he creates all these characters and then makes a whole bunch of absolutely ridiculously contrived and coincidental links between them all.
Example (without spoiling too much): In the Fallon Legacy, the daughter of a friend of one of the main characters runs away, and then just so happens to meet up with and marry the best friend of that main character's bastard son.
I realize that all fiction requires some coincidences to drive the plot (if this one guy doesn't save the world, someone else will and the story will be about the other guy instead), but I find Robert Jordan just flat out abused the whole concept. The example above isn't even really key to the plot - the subplot of that girl could have ended at "she ran away", and the story would have been no different. Instead, Mr. Jordan decided to write another tenuous link between characters, seemingly out of thin air.
