well I want differing opinions. Different takes on the WoW universe.

I just don't want any more from Knaak.

Even if it means less books, I would love this.

Also, make them longer.

I don't necessarily think letting him write books is the problem it's which books they let him write. Let him write about dragons all he wants. The Aspects presence in game is fairly limited until recently. Since he had a hand in their creation let him help develop the characters. The issue is giving him characters that have well developed in game presence. I enjoyed War of the ancients, but the lack of congruity with the characters we saw in Warcraft three and the inclusion of characters outside of the timeline, and most importantly lack of trolls, was disheartening. Let knaak play with characters all he wants just don't give him the ones that are already well thought out.

Scratch that. I would welcome some more Jeff Grubb. I loved the hell out of The Last Guardian.

Agree 100%.
Make it so.

That's fairly simple to answer. They let Knaack keep writing because Metzen is a fan of his work. I bought the Warcraft Archive and there's a whole forward of Metzen geeking about how much he loved what Knaack did with Dragonlance.

I don't mind multiple authors at all; Warcraft is big enough to handle maybe 3 or even 4 good authors. But Christie is at least twice the writer that Knaak is and it feels like his writing does nothing but drag the universe down.

Knaak words for cheap would be my guess
