Not accurate. His whole "Taveren-will-stop-your-heart" thing was a super-evil way of saying "treat me as the supreme ruler I am".

Even after becoming good again, he schools Cadsuane to get her to call him Rand Sedai (frickin' awesome scene, IMO).

Point being, Egwene amkes some annoying decisions, but she's also one of the more capable leaders amongst the AS (partly by virtue, largely by circumstance). Until the WT stops becoming so wrapped up in scheming, having a dictator is going to be the most reliable way to ensure the WT actually DOES anything.

I think that Egwene isn't entirely mature in how she sets her goals, but I think she isn't out of line in this case and the means she uses are fine. She doesn't bully Nynaeve, though I imagine that if their situations were reversed this might not be the case (which is hard for me to say since I like Nynaeve much more).
