so i started as oda in 1551 and went on my campaign to subjugate japan, when i got to about 33% a vassal under my son died and left his realm to another guy, and bam he suddenly has 12 provinces. now my army is busy chasing after rebels all the time and i barely has any time to launch new campaigns. and worst yet because he's a subject of my son, i cannot directly deal with him! i was thinking about killing the guy off with ninjas so the land might be reverted to me and i might assign to someone else, but as you know they take forever to find when i really need them. so the next best thing to do, i guess, is just sit around and let rebels take them over, and go through a natural selection process? lol.
