Did you try smuggler ruffian discipline (operative lethality)? It ranks as one of the highest dps in PVE, and it's quite fun to play. There is an ability to insta-get TA, but otherwise you just use blaster whip/shiv to gain TA, the rotation is very simple, just keep DoTs in place and spam brutal shots/corrosive assault. Otherwise, the mobility is awesome. There's an utility which enables quick shot to kick back enemies after you scamper once. I love it I get your point, in my experience guardian vigilance, smuggler ruffian and commando gunnery are the least complex in terms of how convoluted the system is. They even removed some of the stats like Cunning and Aim years ago (check this out).. Unfortunately you're joining us after years and years of class changes. Maybe vanilla swtor is something you'd appreciate more? And Onslaught is dropping on Tuesday with a whole new gearing system
