Blizzard's Tom Chilton has been making the rounds this week in one candid interview after another. World of Warcraft website Icy Veins recently asked him directly why recent content releases haven't been meeting the originally planned six-month cadence, and Chilton didn't dodge, explaining that scaling the team up to make Warlords of Draenor resulted in a slower-than-desired pace for releases:
We did a good job earlier in Mists of Pandaria, having the content come at a more frequent intervals, and certainly we had hoped to have Warlords of Draenor out a couple of months ago. The reality is that scaling up the number of people that we have, to work on multiple projects at once has slowed us down. Honestly, it should have not come as a surprise to us. We increased the size of the team by 50% and the majority of those people had never worked on World of Warcraft before or any other MMO, so it is really difficult for them to create content right away, without getting up to speed. So we ended up redoing a lot of the content that we were doing for Warlords to make sure that we would get it at the quality level that we would expect. Also, the garrison feature turned into a bigger thing than we expected it to be. Quality is the most important thing, so if we have to make a choice between getting you something two months ago or getting you a great expansion in November, the choice is obvious. I think we are in a better position now for the future, we already have zones in production for our next expansion. So, if things go well, there will be less of a gap.Chilton also discusses alternative subscription models for niche players (there are no plans for such), the possibility of making Outland and Northrend parallel level 60-80 content paths, and the potential for visual and aural upgrades beyond character models.
