I'd like to see some limited transfers allowed to Imladris.
Open up transfers for players who have a level 50+ character on Imladris to transfer characters of theirs from other servers. Allow this for a week or two. These players already understand the community of Imladris, so allowing them to transfer some of their characters from other servers should do zero harm to the Imladris community.
If you're worried about economic issues, only allow them to transfer with some maximum amount of gold (perhaps 50-100g) and only what is in their bags (i.e. no vault storage or housing escrow/storage.)
