We did, however, add Black Hole Commendations to the weekly Explosive Conflict mission, so you can also obtain the Commendations that way.
"Added it"? Isn't this the weekly quest that if you progressed a certain distance in the operation (be it story mode, hard more, or nightmare mode) you would complete the quest and get BH comms?
If so, that's always been there so there was nothing to add. The only thing different in 1.4 is you made it easier to complete by making it the Tanks instead of the Colonel to complete the quest and through in some Daily comms I think. Still, you didn't add BM comms as a reward, you may have just changed the qty.
Correct me if I'm wrong.
