You must remove the ban on deleting characters over level 40. By having such a rule you are LIMITING game play to that level. Most of the fun is starting a character over fresh, but by having such a rule you are preventing that. Instead over time a person will use up all their available character slots and never be able to reuse their favorite character names. This problem is FAR worse that any perceived problem you are trying avoid. PLEASE REMOVE THIS LIMITATION and let us delete our old characters.
