The "handsome rewards" aren't.
None of my Assignments give rewards that are higher than the cost of the items to build. For example, one of them wants 16 Internal Forcefields (1875 each) AND 14 Improved Alloy (1000 each). That means that it'd cost me 44,000 to build all of them. Unfortunately, the reward is only 29,316. This means it'd cost me about 14K to do the Assignment.
I don't see the point.
Is there some reason to spend more credits than the reward? Is there some way to reduce the upfront cost, or do these assignments stack up to something more significant making it worth the expenditure?
