That's why I believe it's going to be a very late beta access, similar to BF3 or TOR access. Get in for a few days, a couple weeks before release, get wiped anyways. They won't actually expect you to test things out, despite the name of 'beta testing'. It'll be a very very late build that you'll have access to. The idea of paying for a beta slot essentially means you can't expect to get bug reports, people are paying to play the game instead.
