In terms of a fix, I could think of several ways (or a combination of them) to make cooperation less efficient:

a) Modify the scoring to make cooperation less valuable. E.g. defending = capturing, or increasing the value of defended cell the longer you hold it, etc.

b) Match anyone to anyone. If devs are so inclined, scale everyone to the same baseline. At least expand the band of the guilds match-maked against.

c) Add a difficulty modifier based on the historic standings of your opponents.

d) Hide the opponent names for the first few rounds of each war. Makes running ghost guilds more difficult.

e) Make neutral faction more active/aggressive, contributing more to the war strategy and scoring.
