well, other than keeping your gear up to date, there isn't much else you can do. I've played a Jugg tank but she's still on Nar Shaddaa, having a healer companion makes a huge difference, same with wearing blue gear as compared to green. What level are you? do you have Doc or get him soon?
Im lvl 22 on Taris now, I do try to keep my gear up to date but most of the time I just postpone and say to myself I should still wait a few more levels
