Changing GCs

[Victor]

I'm planning to switch between all the GC's for achievements, so I'm looking to confirm all the cons before doing so. Looks like the main one is having to wait a month before switching again. I wonder if I leave a GC that I'm already capped out on, and then in a month come back to it... Would it still have the same number of seals and ranking that I had a month ago before I left? Sadly, I guess nobody has an answer to this one yet.

What are the requirements of ranking up to Second Lieutenant anyways? People in this thread are making it sound terribly difficult but I didn't think it was.
