This is a complaint I've had since beta that I still don't understand the lack of movement on.
Once you accept a mission, there is absolutely no way to review what your rewards are going to be for that mission except by dropping the mission and taking it again.
This is just plain idiocy, to be blunt about it. The items, skill points, credits, dilithium, etc. for any given mission should be listed in the active mission summary text.
Why can't this be done? It's a HUGE quality of life improvement for what I would expect to be relatively little investment of resources. If you can list rewards before the mission is accepted, why not after it's placed in active status?
While I suspect this won't even be considered for the F2P launch, could it maybe be put on the schedule for future updates?
