Agree with @TVF. If they wanted to populate the ships table they would have put most of the recent releases there, but they didn't. Most went to hard nodes which already had characters on them, rearranging everything in the process.
They're very selective of who they put on ships. Double the refresh of regular energy, which basically negates most FTP (**NOT ALL) players from refreshing ships energy for only one more set of sims per day. Why do 100/5 when you can get 50/5 on regular energy where there's much more to farm?
I can't remember the last time I refreshed ship energy with crystals. Can't be bothered.
