1: I'm confused with the levies change. The patch notes just stated: "You only raise levies from your direct vassals, and they are not directly connected to Holdings". Does this meanyou won't get any levies from your indirect vassals anymore? That seems just weird and unrealistic. If not, do you get levies from your indirect vassals proportional to how much levies you get from your direct vassals times how much levels your direct vassals get from your indirect vassals? That would be just like taxes, the levies your direct vassals raise from their vassals would be counted towards how many troops you can raise from those direct vassals, and you get a certain proportion of that. It would mean the opinions of your indirect vassals are largely irrelevant though. It also still means you get punished for having many "layers" of vassals, since each level only gives a certain percentage. Another option would be that you actually still draw levies from all your vassals depending on their opinion towards you, but they are just immediately added to their liege's levies for convenience. I really don't which (if any) of these possibilities is in the actual game, while it is quite important to know.
2: How exactly does the formula for how much % of troops you can raise (work? It seems the one on the wiki is outdated. What I have figured out so far is the following (let's assume we are drawing levies from a direct vassal): the minimum you get is set by the crown law, and the maximum by a certain number depending on, but not equal to, their opinion towards you times how much percent you claim via your regular laws. I'm mostly wondering how the number depending on your vassal's opinion is calculated, and when it would be wise to set your recruitment laws higher or lower. If you increase the amount of levies you want to raise the minimum amount you can get stays the same, and for the maximum the opinion modifier goes down but the amount you claim via your laws goes up, so it seems like nothing really happends.
3: is there any thinkable scenario in which you would want to execute blind or castrate someone? It seems to me that if you are not going to just release them, banishment is always a more profitable and less tyranny invoking option. In the rare case you are so scared of your prisoners that you do not even dare to banish them, you can just let them rot in your prison for the rest of their lives without any risk of them escaping, and without invoking any tyranny. Am I missing something here, or is it just plain bad to execute blind or castrate someone?
