Ok I worded that wrongly, I will always wear my pve gear for pve, expertise is useless in pve.
What I meant was which FP or Ops do I start with as a reasonably new level 50?
I have 3 50's and 2 30's but never really grouped up to be honest, I seem to play a class, get bored and move on.
I really like my Shadow so I want to progress with her I'am just unsure where to start.
