Partially it's an effect of the end of any series of books. Even if RJ had lived to complete his series we would likely be bitching. There will always be fans who don't like the outcome the author has written. Cannoli will spend the next 20 years bitching about Egwene no matter what she does in AMOL ... He hates the character and will find new and inventive ways to vilify her ... Doesn't matter who wrote her last words in the series. I'll never like Cadsuane or be happy that Moiraine came back from the 'Finns so weak in the Power. I hate that Egwene is with Gawyn, or that Min can't channel and will die hundreds of years before Rand, Avi and Elayne ... Many people wanted Verin to live or Galina to die or Siuan and Leane to be Healed to full strength. The list is endless and we all have our things ... Sanderson just gets the double dose because he's not the original author!
