I couldnt find it in the search, I noticed you get a ques to add a socket to your sha touch weapon. I did it on Ally then when I faction Changed and I was able to do the quest again to add a pris to my weapon.
I had used my first on on my LFR weapon, when I faction changed I went to see if I could do it and the quest was avail I did Change of Command again and got a 2nd Eye.
