What I am hoping Bioware will do is just hit the reset button completely on Nightmare Mode. Go back and redo all three of their existing instances to make Nightmare Mode fights with new mechanics for EV, KP and EC. Spread the new tier of gear across all three instances.
If they did that, then they would give guilds clamoring for hard content a bunch of bosses to chew on that would easily last us until the next Operation is released.
they would be smart to do this. all 3 existing operations with new Nightmare difficulties which would be tuned
to the new level cap, etc with different mechanics, etc.
