So it’s GCD this week (yes, it’s that time of year again) and Blizzard’s own Tom Chilton has given a fascinating talk about World of Warcraft’s evolution and the changes that have taken place since Deathwing’s return. Well WoW Insider has a pretty comprehensive article looking at the talk which includes the redesign of zones like Desolace and Westfall, as well as the redesign of the talent trees. Barring a transcript of the actual talk, it’s well worth a read.
