Not sure if this will be read.. but i feel that the new duty officer system takes way to long to rank up!!! I really think that the levels should be lowerd so it's realistically obtained. Would really like to reach the first level in the duty roster system before i make it to VA.
I'm wondering if they can't add alternate means of achieving these goals like with Fed Diplomacy. You can do scientific missions or military missions or what have you to earn additional points toward the crew ranking systems.
I transferred over a max level Fed and made rank 1 Medical and rank 1 Diplomacy after three days. That's without focussing especially on those categories. Clearly a lot depends on your Doffs (I spent a lot of EC on the Exchange buying Diplomats) and there's not much you can do about them early on, but three days doesn't seem excessively long for two rank-ups. If you focus on particular specialists I'm sure you could do it faster, Science and Exploration have short duration missions.
I also started a new Fed character and stopped doing normal missions with her at level 8. She just hit Lt Com this morning (also 3 days), but doesn't have any Doff ranks yet.
