A few weeks ago I started my grind of Federation ranks to get the corvette. Once I got to Lieutenant (Rank 8), I took a break from the grind. I came back today to try again. After putting in about 10 hours of grinding and over 100M credits from donations, I have only ranked up about 1.75 ranks. I know that the higher your rank is the more missions it takes, but this seems excessive. I have pretty much been doing data delivery-type missions and donations. I did this grind for the Empire during the break, and it did not take nearly this long. Am I doing something wrong?
