Would replacing Blücher with Goeben have made Dogger Bank much harder for the British?
Short answerIt would make the forces more even and might raise German speed, but the British would probably retain the advantage.
NotesA single ship substitution would not completely reverse the battle. A more modern battlecruiser would remove the slow and vulnerable armored cruiser from the German line and improve the tactical balance. Even so, the British probably retain enough advantage that the encounter remains dangerous for Germany. The answer separates fleet-wide conditions from the familiar focus on Blücher's loss.
