I am a LT Commander 11 now. I thought you did your 10 grades and your promoted. At least that is what it did before when I was a LT. It says grade complete but still need to spend so many points. I have no more skill points to upgrade myself or crew. So does that mean simply I need more missions for more skill points?? I am pretty far along in the missions and even getting some mark V stuff that I cant use yet.
You might just b e at a point where you don't have enough skill points to spend on a skill. And you still need to spend like 10 more points to official reach the new rank. You have to have spent the at least the number of points needed.
