The Wakfu site has been updated with a new developer blog to show off some of the big features that are being retooled for a December release. Nearly every aspect of the game is being reworked to provide easier exploration, better progression, improved monster families, the inclusion of new dungeons, the addition of new and improved equipment, more streamlined questing, revamped UI elements and much more. These improvements will be spread across the game's four main nations.
The four updated nations will be smaller (less surface area) because we want to make navigation easier (getting around will take less time), make content more concentrated (less "empty" and "unnecessary" space), and encourage interaction among players (who will have a better chance of crossing paths and interacting).
Check out the lengthy and informative post on the Wakfu site.
