What if HMAS Australia and HMS New Zealand had been Lion-class battlecruisers?
Short answerDogger Bank would be more dangerous for the Germans, and the larger ships would be much harder to give up after the war.
NotesThe counterfactual gives the British force larger and more powerful dominion battlecruisers at Dogger Bank, increasing the danger to the German squadron. Ships of Lion-class value would also be politically and strategically harder to surrender after the First World War. The tactical advantage continues into the later fleet-retention debate.
