"Missions are something very different, and for missions to make sense, you have to understand the base concept of crew skills, which is that you are not the one doing this stuff. Your companion characters are the ones who are going hands-on and doing the crafting," Erickson says.
In terms of TOR's PvP implementation, Erickson illustrates BioWare's goal of making the mechanic appropriately contextual to the Star Wars universe (as opposed to the kill-everything-moving-just-because mentality common to many PvP systems). He describes everything from slicing terminals to seeing turrets move in real time, painting a picture of an immersive PvP experience that makes sense within the framework of the license.
Finally, Erickson talks a bit about the recently announced race/class combos, including the Sith pureblood. Check out the video after the cut, or at G4TV.
