My ship crew has been stuck at 4 stars for ages now while the captain keeps gaining. Had me wondering. Is there a cap to how good the crew can get? Crew members are about to hit 110 xp and they've been at 4 stars (either 4 for one job or a mix 3+1 etc) for a very long time.
The only exception I found was at brass citadel. There's a 5 star (3+1+1) recruitable member there but she's not getting any better since I got her either.
Edit: Just to answer my own question after completing the game, yes 4 stars is the most they get (with one exception at brass citadel) at 25 crew xp iirc. If you want a 4 star deckhand for example, you need to grab one that ONLY has deckhand star and nothing else.
