Honestly I like this game rules. It's an interesting premise. I would definetly want to be on the sailor team since the pirates only have a single vault. That is in some way an advantage since they only have one spot to defend but that also means all it takes is a single fuck up and they all potentially lose. The sailor team has a margin for error since they have 5 of them. And nothing is stopping them from just grouping up at a single vault since they only loose when all of them are destroyed. They can start with protecting all 5 of them but as any get destroyed the people there can just reinforce the other remaining ones assuming they didn't die. And honestly having to grouping up at a single base is more a disadvantage than an advantage. Since D-Game players aren't exactly the most "co-operative people" and even if there's a penalty for killing teamates I'm sure some will just ignore that and do it anyway. With 5 bases they are more split up and there is less chance of conflict as you can choose to stay with the people you can stand more. The only real disadvantage that the sailor team has is that they don't start with a key. But all they need to do is steal a single one of the FIVE keys and that disadvantage disapears. Ofcourse these game always have some hidden bullshit in them and once that's revealed I'm sure my speculation will go out the window so I guess we will see. Also I guess you can really call Shuka a "D-game player" now after this episode ( ͡° ͜ʖ ͡°)
