Here is from my draft:

> Ranks are given mainly by clustering firepower + torpedo points within a class, possibly with an extra ☆ star for ships with high initial luck or special abilities (see tooltip notes for that). The only exception is Akizuki-class DD, they are ranked high solely for their special AA CI.

So either luck or some special ability that you can see in a tooltip (like opening torpedo for Abukuma, 4 slots for Yuubari/Ooyodo or strongest AA CI for Maya).

It also seems that I need to rank Hatsuharu as 3 star and Ushio as 1 (+ ☆ star for luck) to be fair.
