Judging by the Legacy-->Official, and when Small tribes was released, it's obvious how much fun there can be had when the main game itself is wiped or has new servers. However before this can happen again, there really needs to be more measures taken for various issues such as duping, character loss etc. Economy and resource management should be a key part of the game, but it's not, and hasn't been for a while now. Genesis didn't help in the slightest, people were able to get mass points, dupe their character, and essentially have infinite of any resource found in the Hexagon Exchange. Likewise, people are still using their duped materials from over a year ago.
The legit players gets filtered over time naturally when these things aren't fixed. If you look at Small tribes on PC right now, basically every 'big' tribe is cheating one way or another. Legit tribes simply cannot compete. It's like people are actively trying to break every single dot point found on the Code of Conduct.
So yeah, a wipe is really needed if you want to see legit players come back to the game.
