Demandred spent the series secretly building up a huge army that greatly contributed to the Shadow's cause at the Last Battle. He brought in Taim, killed Gawyn, defeated Galad and Logain, and essentially out-generaled Mat the entire time.

Graendal sowed chaos, manipulated events from afar, harassed Rand the whole time, and despite falling into disfavour from a failing, came back to sabotage all the Light's great captains and meanwhile engage in fighting herself at Shayol Ghul, running the Light's forces ragged. She was defeated by a twist of luck, not by being outmatched.


The rest were pretty much useless.
