Please don't do that! Many of us are
very attached to our names and spend days/weeks/months thinking of the perfect one (I know I'm not the only one in LOTRO who has read several dictionaries from cover to cover several times just to be able to build the perfect name).
Among my friends I've seen many disappear for a long time due to RL stuff like having to focus completely on their education or health issues and such, and when they finally can play again they'd be very upset to suddenly have lost their name. And I'm sure that some who return will leave again when they see that someone else took their name

And that their old friends won't recognize them anymore.
LOTRO is a special type of game, I have often seen people on my main server who comes back after being gone a couple of years, lured into the green grass of a new game, and then they got tired of it and they remember all the fun they had in LOTRO so they pop back in again. Don't chase them away, please!
Also, when I chose a game to play one of the things I looked for was that the characters can never get deleted (taking away the name feels just as bad to me) because before that I had been playing games where you had to log in every 6 months or so or you'd loose them. That made gaming not fun at all for me. It became stressful work where I had to schedule a day here and there to log in my many many many characters so none would be touched.
I want to be able to play the character I feel like playing, and I don't want to have to keep notes where I write the date next to the character's names to show me when I last logged in so I can make sure none of them accidentally gets no playtime due to me feeling like playing other characters and then poof one day, name gone
I understand that now while the transfers are happening it'll be a bit sticky for a while since so many have to move around, but that's OK.
I don't mind working to get what I want, but please don't become one of those games where you have to do hard work just to keep what you already have. Please?
