The gear players receive in World of Warcraft has undergone change after change over the past few expansions. Hit and expertise have changed functions and values, Spirit became an option for caster damage classes, Mastery gave us more diversity in gear, and much more.
As well as all the visuals revealed at Blizzcon 2013, the developers have also had a great amount of information to deliver about the sound and music in World of Warcraft. Some of it might seem incidental, but some of it is quite exciting.
Phewph, I need a break. While I recover from this information overload induced coma, take a look at the developer interview from Blizzcon. Once I’m less dead, I’ll jot down what the developers have cleared up.
