the biggest fact is that it is unfair to let some play 7days early and not others. This is the only time I have ever seen a new game do this and I think it is wrong and unfair to all thos that have preordered.
When I get my invite I know I'll be getting on a new server that just opened up. So not worried about naming and since a big chunk of ppl will be on the first servers queues should be lower too.
