Which wartime ship classes should have been replaced?

Which Second World War ships did not need to be built, and what should have replaced them?

Few were obviously pointless at the time, but late escort carriers, Audacious, and Atlanta are plausible candidates for different allocations.

Hindsight can make ships look redundant even when they answered real wartime needs at the time of ordering. Candidates nevertheless include late escort-carrier designs whose added complexity offered limited gain, replacing the Audacious class with Malta-class carriers, and questioning the top-heavy Atlanta class in roles it was not designed to perform. German capital-ship alternatives also illustrate how available guns and shipyard capacity constrained supposedly cleaner choices.
