WoW Insider: Blizzard seem to be treating each major patch as more of a mini expansion, what are the reasons for this?
Tom Chilton: I would say the biggest reason is because we're always pushing ourselves to do as much as we can in every patch. We're never really satisfied with what we have in the patch versus what we didn't have. Maybe the developers get a little out of control - but in a good way as that's good for players. More than anything else we want to make sure that in a patch we have content for everyone.
We feel like one of the things we didn't do so well in the past was to deliver content for everyone, we would deliver content for different parts of the player base at any given time like a 25-person raid or a 10-person raid or here's a new battleground, back in the day of Arathi Basin. However we didn't really hit everyone at the same time so we're trying harder to do that while at the same time maintain our pace of Expansions ... our blindingly rapid pace of Expansions.
