World of Warcraft: We ask the devs what's changed since Warlords of Draenor

As Eurogamer's Oli Welsh explained back in September, World of Warcraft: Legion had an incredible launch. Artifact weapons, class halls, loads and loads of demons - it had it all.

However, in stark contrast to Warlords of Draenor, Blizzard have also nailed the big patch content this time around. We returned to Karazhan last month and Blizzcon saw the reveal of Patch 7.2 and the Tomb of Sargeras. WOW players are having a really excellent time.

I chatted with lead game designer, Matt Goss about how the team managed to pull this off. What's changed to allow for this level of quality and quantity of updates?

Oh and I do ask him about Legacy servers too, but unsurprisingly they're not interested in talking about that just yet.
