1. SE is working on way to handle that.

2. Would piss off the community of the server your transfering too. Would you like it if they add new wards on Balmung and said you could not buy them cause their for players transfering in? Pretty sure most of Balmung would be pissed..

3 & 4. Not going to happen. Researching a server before transfering is not hard, every server has its own forum post questions and get information. If you can make an alt on the server you wish to transfer too and try it out. If you transfer into a high pop that is your choice; never transfer to a high pop server unelss you are willing to deal with the circumstances of that choice.
