I can't decide if it's goblins/more gold or success chance. I mainly want gold but I wouldn't mind some perks on the side, especially if they can be re-sold for gold. I'm thinking of dropping the trolls at the moment (extra equipment) and the tauren (experience) and the blood elves (shorter duration).
Personally I'd go for success chance. The gold from shipyards isn't great, and I don't see pure gold missions that often. I'd rather have a higher chance of completing awkward rare missions.
Definitely agree on getting rid of Tauren, Troll and Blood Elf crews (in that order).
I noticed a problem is that some high gold missions can't be fully countered, maybe not even fully with +chance. Then again, they might be worth 'unsinkable'. Those too though have the problem of reducing the chance enormously.
Only 1 ship and sub can have murloc crew just like Awakener ship
Most of my ships are with undeads
Also have 2 trolls but thinking to replace these with BE for faster missions
