Mogami improves the formation by supplying hulls for dispersal, layered defence, and mutual support between ships. Equipping every position with a Maya or older Kongo equivalent would raise costs enough to prevent buying the required numbers. The high-low mix balances individual capability against the size of the force that can actually be fielded. Mogami earns a favourable assessment as the lower tier within that arrangement.

Hull numbers for dispersal and mutual support
More affordable escorts allow a formation to disperse and support its defensive layers; equipping every hull like Maya or Kongo would make the required fleet unaffordable.
