I could care less about the auxiliaries thing. We need to get Academy Expansions now or we run out of crew and you think having to borrow freighters is embarrassing? Just wait until we hit a genuine crew crisis.
It's not an either or situation. I agree with going for an Academy expansion in 2314, along with some new shipyard berths, and replacing Seruk.
Request development of Utopia Planitia, 35pp, (4 turns, gain 1 3mt, 1 1mt berth)
Request new Shipyard at Ferasa, 25pp, (12 turns, 1 3mt Berth)
Request Academy Development, 35pp (Gain +.5 Officers/Enlisted/Techs throughput)
Arrange to have an Old Guard Admiral convinced it is time to retire, 20pp
There, that's 115pp and a perfectly reasonable list of priorities, I think.
