From the standpoint of a player returning from Hiatus, I say the idea has merit and promise. Count me in, for all the good a level 39 Ninja will do in the short term.

Returning to the game, starting a new character, and running through the story content again up to the point I have, the idea of getting to experience the content I missed in the format where it would be a challenge is highly intriguing. The couple friends I've come back with are similarly enjoying themselves with the content, and I think they too would be very interested in the idea of the game having a backlog of content which can still be challenging and fun. And while I obviously can't speak for anyone other than myself and maybe my personal few friends, I would think there must be at least a few other latecomers to the game looking for a place to learn and some content to experience from patches prior.
