Lol at all the people going "OMG amazing trailer. This expansion will be GREAT!", as if the two are even remotely dependent on each other.
That said however, this expac looks pretty cool. They seem really determined to fix most of the glaring problems this disappointment of a game has. Removal of the Auction House and perhaps some changes to the skill system (which is pretty uninteresting as it is now) would seal the deal for me.
Looking forward to hearing more about this.
