I wish they would put out more videos showing in-game combat for the various classes. So far the stuff has looked pretty safe and boring. IE, I've never seen anyone actually struggle to kill something whether in a group or solo.
They had one fairly good video of a group doing a boss encounter a month or two back...but it seemed very staged. They had people playing in a way to show off the encounter and try to make it more exciting...and even then it was pretty boring.
I do however like the idea of their ship being crewed by their companions and they can have the companions do stuff for them while they are logged out and other options. That's pretty interesting sounding, although I wonder how they will balance that out having 100k people doing this 24/7.
