Sith warrior, also can go as juggernaught or marauder, but id like to outpoint the marauder itself.
Starting off, marauder is a pretty hard character to handle, most ppl considered it a broken class, as in worthless class, mostly imo because they didnt even know how to friggen use the character, they had to many skills to use, and just couldnt face it, its those ppl who acctually wanted to play something easy, like a bounty hunter arsenal for example (press the tracer spam) indeed, it only requires one button to play it wonderfully....
But lets get past that, marauder is a pretty hard char to control, you have decent utility on him, as in intrerupt, cc( force choke, can be considered) and mass cc ( intimidating roar) wich are its main asset in disabling opponents, and not to mention, force camuflauge, the skill that rlly makes ppl go mad, since u just vanish for 4 seconds, and can make a get away, and above that, reducing all incoming dmg by 50%.
About the attacking skills, its a pretty vide scale, depending on each player what they prefer to play as a marauder.
Either use dots to take down your foe, or use a slight boosted dmg while u focus one target, or just mass damage a whole group that is near you, and nuking them to oblivion :) But getting past that, the marauder not only he is a good dmg dealer, it also has a pretty decent defence, and can be used as a great asset along warzones. They can hold quite some dmg, and allow the range dps on theyr team, to focus down targets fast, while the marauder just grabs everyone up from the opposing team. Mostly, marauder is the class that gets alot of focus down(along a healer), usually because,if they get ignored, they can wipe out alot of targets, if they are played properly, so a marauder isnt a class that you rlly want to ignore, especially if we are talking about a nuker builded one.
Currently in swtor, since 1.2, marauders got enchanted big time, most ppl contesting againts it, and i do not blame them, since it is true, if a marauder has all his cooldowns, and every trinket avaible, he could kill any type of class, in a 1v1 fight. Some people might disagree, i tend to consider the opposite.
