We’re trying to build out an entire world. Some locations will feature hero backstory in the forefront. Other locations are places we want to develop over time. We also really enjoy hearing what our players react to… it inspires us to chase directions we might not have otherwise
He also clarified that Blizzard are always looking for community feedback. They appreciate inputs from all quarters and as such the developer team looks forth to improve their Game title.
