So I did this a couple of times today and, much to my disappointment, it only drops MK IX items.
I expected that given the LTC version drops MK IV that the Commanders would have VI, Captains VIII, and Admirals X.
I was better off farming the Lt Commander version at this rate. Given the HP boost it now takes 20-30 minutes to kill as opposed to 2-10. Not to mention since I usually get stuck tanking the beam until 60% I have to switch out another ability to jam it.
Are any Admiral level fleet actions giving MKX blues?
