If Angron struggled to lead a small group, how could he be expected to understand running an empire?
Short answerSome of the Imperium's leaders were suddenly given roles for which they had not been trained. That lack of preparation is treated as an institutional problem.
NotesThe objection concerns the gap between leading a small group and running an empire. Some of the fictional leaders suddenly find themselves doing jobs for which they were never trained. The criticism therefore extends beyond an individual's shortcomings to the Imperium's limited provision of training. Appointment to a larger command does not by itself supply the preparation that role requires.
