That is why it's a beta. They are purposely pushing their servers as hard as they can so they can get as many bugs fixed as possible before the launch. The play-ability at this point is not how it will play when it goes live. I have been on the beta for a couple months and can tell you I have seen huge amounts of improvement as we get closer to launch. I have no doubt that they will have a smoother-than-expected launch.
