I want to play something that is primarily for PvE and also something that is fairly easy to learn.

I am having a lot of fun play sorc right now, and I was wondering what the best options for modifications to orange equipment are to achieve the best DPS. I don't care about PvP, as I prefer PvE.

I was subscribed right before Knights of the Fallen Empire came out using the two-month none reoccurring. I lost sub before Fallen Empire came out so I dont have access to it, but for some reason I cant play through Shadow of Revan. I can play through Rise of the Hutt Cartel, but thats it. My characters are also capped at 55. Anyone know why this is happening?
