I had an idea to help spark interest and increase traffic in older zones. You could have a Zone of the Day. Every day a different zone (no starter zones) would be featured and you could offer various rewards in that zone. Rewards such as 50% bonus xp, 25% chance of double drops on nodes. You could also create a loot bag that has say a 20% chance of dropping from bosses and 10% chance from nodes and 100% from a daily quest. Inside the bag you would have a chance at acquiring a number of possible rewards such as style mats, alchemy mats, upgrade mats, treasure maps, style pages, motifs, blueprints, with more valuable rewards dropping less frequently. I'm sure the community can offer other ideas for rewards in the zone of the day. Not only would this offer us a good reason to explore old zones but the increased traffic will help people who are looking to complete world bosses, dragons and Harrowstorms that require multiple players to complete. There are over 25 non starter zone areas so each zone would come up approximately once a month in the rotation. A zone of the week I don't think would have the same effect as peope would get tired of it after a few days and the zone would only come around in rotation twice a year as opposed to once a monthish.
