Are you doing any crew skill stuff? How much PVP have you done?
I have not touched pvp. I have been doing crew skill stuff but you can do all of that while you are playing with no downtime. I have the non-combat companion doing stuff almost all of the time, and my main companion doing stuff when i am turning in a series of quests or running a long ass way. I have not run into the 3rd companion where ever that is.
