Should I wait for 1.6 to start my sub? I (and a few friends) have keys that we bought back during the sales around Christmas that we haven't activated yet because we were waiting for everyone to get done with all of their familial obligations, etc. So now we're thinking we might be ready to all settle in and play, but I'm seeing that there is a 'massive' 1.6 patch on the horizon.

Is the patch going to add or change anything significant enough that we should wait for it to be released before we start playing?

Side question: Do I understand correctly that there is only one server for NA?
