Why not use later Austro-Hungarian or French hulls in Ultimate Admiral: Dreadnoughts to model a Tiger Cub?
Short answerBecause those assets introduce anachronistic or foreign design assumptions; a scaled British Tiger hull better illustrates the historically constrained Royal Navy concept.
NotesUnlocking a 1930 Austro-Hungarian armored-cruiser hull would import a country and design path that did not historically exist in that year. A 1920 French hull is less anachronistic but still embodies a different hull shape and national design tradition. The purpose of the exercise is to illustrate a plausible British Tiger Cub, not merely to find the game asset that makes the build easiest. Scaling down the British Tiger hull therefore preserves the historical question better than selecting a superficially convenient foreign model. The choice demonstrates how a simulation can support historical analysis only when its assets are constrained by the technology and institutions being studied.
