I feel the Jugg is not too bad for leveling. It is centered around the Smash, Sundering, Force Charge, Force Scream and Force Choke abilities. It took me a while to understand that you have to build up rage and then unleash attacks on your opponent (lol). Also using Saber Ward as your saber block like in SWG. But, after tinkering I found Jugg rewarding. Consequently, Defeaning Defense helps you later as well as ruin which takes the rage cost away for Smash. Jugg is all about timing and knowing your enemy. It may be a little more of a challenge compared to some other classes, but with time i'm sure jugg will be considered a decent class. A balance of both the Immortal/Vengeance Skill Trees Works Best. I am putting 27 points into Vengeance and 14 points into Immortal. What I noticed helps as well is leaving points out of Shii-Cho and putting them into Soresu Form.
Sith Warrior - Hybrid Juggernaut Template
This is a template I found on the web. It is a mix between assault and defense for those that want DPS, but not to be too squishy.
