I propose that ArenaNet combine PVE zones that are essentially empty. For instance, I am leveling a character in Caledon Forrest. I see about 2-3 characters per hour on a High server. I participate in most dynamic events by myself and don’t get to interact with many other players.
By creating a single instance for these leveling zones, it will increase the number of people in them and make it more enjoyable to level with other people. It will put back the sense of community in the lower level zones that was there during release
