Cool name, you handsome devil!
I agree about Legacy plotlines being better, I liked Sam as a sanctioned operative more. Might be why SCC co-op was vastly better than the SP for me. I also want to seee a vastly more diverse set of action elements to further facilitate more in depth and varied play.
What I NEED them to keep is the speed stealth, the option for partial or full on aggro and some of the nice new features and modes.
