Aside from the usual Oil efficient LB0 ships, I've been using ones like LB0 Cleveland as well.
Since such ships are usually the most used ones for things like farming & early Event maps, might as well use favorite shipgirls that one really likes more often then even if they cost a few more points in oil. (Currently thinking about raising a LB0 Belfast)
It really is something when one is finally forced to sell some off out of space necessities.
Those rare gem commissions are pretty exciting when they pop out. So is the anticipation & wish for success upon finishing them.
Speaking of costumes, I'm a little bummed out when I found out Retrofit skins are per individual & not unlocked for all ships involved. Was hoping to change the looks of ones like my LB0 Cassins & not-fully-upgraded Yamashiro.
