I was playing on humankind difficulty and a militarist empire with several pacifist vassals decides to declare war on me. I don't have much war support to begin with, but I choose my battles wisely and manage to win every encounter. My victories grant me war support; however, the AI killing some of my troops in every encounter and the -4 war support for being at war with a pacifist empire always resulted in me losing a -4 to -1 net war support until I am finally forced into defeat. This has got to be an oversight; there is no way that I should be hit with a -4 war support for being at war with a pacifist empire if the liege is the one who declared war on me. Please do something about the war support system for these type of situations.

Really, the pacifist trace should avoid wars, and not to win wars
