The intent with my word blindly was to highlight that sometimes horrible shit happens that people don ' t quite see coming . <| sep |> What if . you have both ? .<| sep |> But will they ever beat Australians at shitposting ? <| sep |> I have absolutely seen it enforced , so YMMV . <| sep |> Felwinter ' s Grimoire has him using a Titan shoulder charge claiming he learned it from Jolder so abilities are apparently interchangeable given enough practice , but subclasses seem a little more solid in the sense that a guardian ' s personality tends to determine which class they stay on longer . For instance , Osiris , who previously was the oldest recorded Sunsinger , is the first one to invent self resurrection , implying by that time he stayed a Sunsinger for the latter half of his life . He also went to Mercury further solidifying his connection with fire . Saint 14 has a defender specific helmet , and his backstory heavily emphasizes defending the city as the number one ideal all Guardians should strive for . Implying that he was a defender Titan . Felwinter ' s helmet ' s flavor text refers to him as . He who stared into the void . The Void is also typically seen and read about in an uneasy manner seeing as how many associate it with the darkness , and Felwinter was known for doing questionable things including being a former warlord . So it ' s logical to assume he was either a voidwalker flat out or at least primarily a voidwalker user .
