First I like the idea, but the execution in my opinion is not worth starting back at lvl 1. The very least you should get a build point and baldric at each 100 level stage. Give me a reason for wanting to play past level 1K. Original conception was to be able to access a new area but that changed to being noble citizen after that was changed there really isn't any reason to continue. It would not be hard to implement a build point and baldric on every 100 levels until you reach 1 k again.
