sounds a little heavy-handed don't you think? each of those chars have equipment like armors and weapons - sometimes lots of those.
Transfer to other accounts? don't go there. even if there were such a thing as a character transfer service, all their untradeable stuff has to be transferred too (not all things can be traded). trying to coordinate that would be a nightmare and a bazillion tickets created when things go wrong (you just know they will)
and what about the guys that don't get the memo that have, say 6 chars, all equipped with upgrades and enhanced boss drops? I can just see the massive rq now.
