An ArenaNet developer is interested in bringing GW1 Build Templates to GW2. What are build templates? They allow gamers to save their skills, traits, etc to their computer as a build. Then they can load these builds at any time (probably not in combat). ArenaNet is looking for suggestions on what else to put into this build feature (like saving Outfits). Feel free to leave a comment for them here:
