Tiger Cub cruisers change Dogger Bank before Jutland

How would Jutland change if the armored-cruiser screen were replaced or reinforced by Tiger Cub cruisers?

Dogger Bank changes first, and at Jutland the squadron adds both combat power and a vice admiral able to resolve a critical command gap.

The counterfactual cannot begin at Jutland because the same cruisers would already have fought at Dogger Bank. Their additional speed and firepower could destroy Blücher and threaten other German ships, changing the forces available later. At Jutland, a Tiger Cub squadron would also bring a vice admiral whose seniority removed uncertainty when Beatty temporarily lost the ability to command from his own ship. A vice admiral could immediately take charge instead of leaving a rear admiral to wonder whether Beatty's last orders still controlled the squadron. Ship design and command structure both shape the result; extra guns are only part of the change.
