Anno isn't vendor with best sell prices...Colenso after finishing Hand So quest becoming best place to sell at highest prices. So she shine only if you come back from planet and want fly to another but finds your invetory is damn full and you need sell something witout finding some merchant on any planet.
Celise do have cum boosting limit...I recall after....5-7 or so feedings she stopping boost my PC stat so after that...she pretty much dead weight for me but she's a goo.... everybody loves them so why kick her afterward? And she can became Giga Celise too
Reaha is friggin Cowgirl and many people are fond of such type of anthro gal. Well I not using too much GaloMax so her free biomass refill not mean much for me anyway. *looks with hope at Savin* cured Reaha when? xD
So those 3 plus Bess/Ben all of them are now matter what we likes and with unlimited crew space there is no reason to kick any of them...and even when restriction will be put in place all of them (checking fast.......) got way to be droped somewhere till we get bigger ship.
Heh I feel that weird itch to say that.... ^^
So what will give you Hand So or Syri that curent 4 crew members can't? Well if you say it's matter of taste/liking/feel I would understand and see as as much valid reason as any other xD
