I absolutely love the new space missions. Took me a couple tries to down most of them, except for that mando one with the asteroid field and mines.. that one took a bit longer to beat. Fun challenge Bioware, please do not nerf!
As mentioned a few posts above me, Nar Shadda would make a great place to have cross- faction dueling, could place it in that big casino.
while having same-faction dueling on the respective fleets as "training exercises".
