I am still trying to get the hang of combat in the single-player game. I cannot quite put my finger on it, but there is something inherently different about combat in TSW vs SWTOR and it is very aggravating. I am currently playing an assault rifle build, and need to try out a melee build before I can make a judgement as to whether or not I want to shell out more cash for slave accounts.

Combat almost seems twitch-based, but maybe I just haven't figured out a way to effectively use mouse-look while in combat (that line-of-sight thing will kill you).
