Option 1.
Why make it harder then needed? I'm in multiple linkshell and I'll probably lose 1 or 2 of them because we'll be splitted up.
The linkshells are pretty big, so it's not to me to tell every linkshell GO THERE!!

I'll just need to choose which linkshell I'll follow to the new server.
That's why I'm completely against option 2. Whole communities are getting ripped apart. =(
