I believe this one was asked before but I could not find the older answer:
browsing through some army lists, I found that e.g. the Khitan Liao (B3. L56) do have ships in their army list but do not have access to sea or waterway. I read terrain placing rules on page 21 in the way that I may place a sea or waterway only if
a) I am the defender and the sea/waterway is compulsory
or
b) I am the invador and both lists allow for a sea/waterway
in consequence the Khitan Liao will never ever see a sea/waterway, their ships can never be deployed. What is the reason to put them in the list? At least from the historical perspective the northern (more chinese part) of the Liao empire can motivate ships in the list AND this part would also qualify for sea (and according to my memory also for WW).
Who remembers the genius/rationale behind this case
