Having The Order offer missions against the Nomads makes a lot more sense than having just missions against the bounty hunters and liberty, or does it not?
i mean, the order is supposed to keep on fighting the nomads in the first place.
right now, it's more like "meh, we're done with the nomads, we just keep on fighting bounty hunters and liberty now, so the nomads can roam, plot and scheme as much as they want."
after all, when you play a strategic game, you don't just stop your offense and patiently for your enemy to recover and build up enough forces to crush you again either now, do you? :-P
