Battlecruiser losses and global reputation

How badly did the loss of three battlecruisers damage the type's global-presence reputation?

Not greatly at the time, because observers largely saw old ships destroyed in a fleet battle for which presence vessels were not intended; the harsher reputation developed retrospectively.

The losses did not immediately erase the type's value for distant-station and deterrence work. Later historical narratives often judge the ships through their worst tactical employment rather than the missions for which they were built.
