There's already a feature like that, called "abandon". It has limitations as well. You see, I would like to have people view the soldiers they recruit as a little more than just numbers, and also not in an american style hire&fire attitude.
Makes sense. My character even does agree with you on that, and treats his men more than that, and even RP's about them.
I've only really had problems recently as I got banned from the realm I was in, and only have a certain amount of gold to support them over a certain amount of time.
This thread can probably be closed in my opinion. My questions were answered.
