Over on our main network site IncGamers.com you can find an interview with ArenaNet and the team behind the game's art/animation. The interview features comments from ArenaNet's Heron Prior, Scott Mayhew, Christian Venturini, and Rebecca Coffman and it's well worth a read. Here's a snip:
First, could you tell us about the animation team, how is it organised?
RC: We are currently a team of six animators. ArenaNet has very little middle management, so everyone needs to be self-managing.
Each animator is responsible for their assignment, which involves more than animation. It’s very important for each of us to communicate directly with designers, programmers, and other art departments.
