I would have loved the challenge. 
But I suppose I can't complain either way.
Imagine that.
You dial up the task group for a frieghter train on Earth and ask the computer to plot a route to Mars.
It gives three or four different routes, choosing between a few different methods.
Direct thrust, Hohmann transfer, Bi-elliptical, Low energy...
Freaking awesome, but planning a deep-space battle? =/ You dial up an enemy fleet and find out that your ships don't carry enough fuel to generate an intercept... and simply have to sit at your planet defending it.
And just imagining an attacker trying to engineer such a scenario... -.-
