Always use Argos to look up armor skins. Most of the set pieces are PVP only. You can’t get the full set in pve. A few of the pieces can be unlocked through completing specific personal story missions. Wiki the individual armor pieces if you want to know the story missions where you can obtain the pieces.
Awarded in PvE for doing level 70+ Personal Story. I can tell you for certainty I got the chest on my ranger at lvl77 story quest.
Mask from lv 73
Shoulders from lv74
Pants from lv78
Gloves and boots are missing from PvE
Oh ok, looks like I have to level a new ranger then because I already did the personal story. Thanks for the replies
You could also level a new thief or engineer, both of those unlock the same skins at the applicable levels.
