I'm trying to change my viewpoint toward my original boffs at the moment.
I got kind of attached to them as well, but really they are little more than any other gear you cary around.
And if you compare your original boffs, most likely common whites or green at the most, to the ones on your waiting list, those will have visibly better passive skills and buffs and usually better original skill training. Blue's and purple's come often enough with rare level III skills you wont get otherwise.
So what I am trying to do is, dismiss the old and make the new ones just as interesting or even more interesting characters.
If you don't want to see the attention you gave them earlier go to waste, you can always transfer them to other (lower level) captains who can still benefit from them.
I think this is what the devs really intended for them originally.
We could even start a BOFF exchange here on the board, where you can post officers you like to sell or, something I would immensely prefer, treat them as a fleet resource for new or low level fleet members and offer them for free.
Unfortunately we can't stuff them in the bank like hand phasers
