I thought maybe you could increase subscribers with 2 alterations on sign-up and one every 25th level so people might personalize thier PC's.
another idea would be Treasure weeks days or even weekends....increase the magical item drop rate for certain periods of time.
Maybe even a once a month drawing for unique items like they do in HR once in awhile.
Anyways these are just a few ideas from me mabey others can comeup with some other suggestions.
