Sith assasin

Looking twoards the sith assasin, i find it a very good class, it is highly considered the most balanced character in swtor, and would like see the Deception class.

It is mainly based on massive burst damage, altho  it has low survivabillity,he doesnt lack the strenght to pin down any opponent in 1 versus 1 fight. It is kinda squishy  if he is being focused by multiple targets, but this build is made to take down tanks and tank healers out there. Deception is based on shock , maul and discharge as rotation,combined with recklessness, it can achieve a high amount of damage inflicted. A good rotation for it would consist in, voltaic slash 2x + low slash, followed up with mind crush and then shock and discharge, will have a huge about of dmg, if not even kill the opponent after done with this rotation.

Marauder rage

Rage spec, my favorite build at the moment. It is massive dmg if you come to twink it right. As rage marauder you want to keep it simple ,altho you will need alot of resources to make your foes tremble.
As rage marauder you want tons of power and surge, you dont rlly care about anything else. But if you know what you are doing you will simply have your crit above low and your accuracy on melee aswell.

Having alot of power ( mostly on all your gear) atleast 68 power on one piece and 48 surge.
You need accuracy aswell, because you have to ask yourself, what if i miss smash? or what if i did use smash but didnt inflict enough dmg? you gotta be aware that your ravage is based on melee ,your vicious throw is based on melee , and they are massive dmg dealing skills, that need to be at theyr hight, because you do not want to miss 10k if you miss smash, right? or you do not want to miss almost 5k dmg if you miss vicious throw right? all these are ment to be held up so you dmg enough.

Swtor Marauder Rage

In this post i`ll talk about rage build. Rage build is a nuking build, wich focuses on taking down theyr targets with massive damage all togheder.
Main skill in rage is smash, with is the heavy hitter. Your skills grant you critical smash for 20 seconds gathered up from (force charge and obliterate) that allow you to crit. 
Further off, your other stacking smash skills are force choke and force crush, wich grant you smash, and when you have 4 stacks, it doubles your dmg on the crit smash. You can roll above 6k dmg on light armor with one smash blow, and over 4ks on heavy armor opponents. 
Not only that,rage is good in team up warzone party`s. it aids your team to toll down quickly whoever is againts you, and nuke them in a large group, leaving them with low hp and having your team finish them off.  

Main problem is having a distance between your opponent and yourself, since you need your force charge at use most of the time, you`ll want to wander around and not stick close, so you have all the utility and use of all your skills, while you are waiting for your smash to charge up and finish the job :) For this build to be quite viable, you`ll need stacking power and surge to add up massive damage ( but i`ll discuss about it in another post).
