I think Luna was/is a great admin. Things are finally starting to heat up on MD after a long lag of inactivity. Unfortunately, Luna was working on someone else's account and the original owner came back. Luna should have worked on his own account and not on anothers.
ALL admins should work on their own account instead of taking over others account. I say, bring Luna back on his own account and not on a cloned account he was working on.
As for the original owner, reset his account to right before Luna took over. The original owner should not benefit from Luna's hard work.
Moreover, what the admins should do is if people are giving up on their accounts, admin should delete their accounts once the owners give notice or if there's a lack of inactivity for given amount of time. Why clutter the servers? Bring in new players who are interested in the game!
As for banned accounts, everyone deserves a second chance, right?
