It's no big deal, but the choice of TW amazes me a bit.
Guest passes might be far more profitable for them.
A guest pass player is a friend of one of the current players which means far less teamkillers on the servers.
Another negative side-effect of the current mass-invasion: normal players stop playing so new players get a distorted view of this game. Making a decision to buy will be influenced by these sub-par circumstances on the servers (teamkilling, no teamplay etc etc etc). A disadvantage which does not exist with the guest-pass system.
I say: guest passes all the way
