Inside the reputation grind there are some ranks that dont unlock anything and are useless besides providing another contract mission for the grind. How about those are eliminated via being merged with the previous and or next, resulting in providing an additional mission every ?th rank. Also the total amount of repu required in total could be shortened by that.
Even with peak efficiency the grind is taking forever. The time requirement required to reach the end of one faction is just inacceptably long.
