If they cared enough to make a story, then the there is no restriction on having the guardians ask those questions. Those are great questions that we ourselves are asking, but you just did it without swaring. It can be done. I can see where you're coming from, but you need to make sure it adds a meaningful addition to the story rather than it being something you think it'd be cool to have. Things like having your ghosts sware, lord shaxx dropping f bombs when it seems a bit out of his existing character, and naked raid bosses sound a lot more like fan service than providing meaningful additions to the story. Boobs hold great power, but they aren't always the answer.
