Conquest of the Horde

Hmm... Does that mean that we'll have to retcon either the Westfall Expedition (Of sorts) into Northrend, or bring Westfall up to WOTLK Lore?

EDIT: Or just leave it?

It says in the wiki that Westfall is now clear of Defias Threat. That means they probably just moved away, as Defias is too large and too slippery a problem to be vanquished. Westfall I believe can be considered Stormwind breadbasket again.

I think the best thing is to simply say that Defias activity has dwindled and that now, for unknown reasons, there´s only the occasional robbery etc in Westfall.
