I want much stronger blobbing resistance.
As a minor part of that, I should not be able to raise all of a duke's levies in the province closest to the action. To compensate for the annoyance, I should be able to raise levies from a province without opening the province interface, and have them automatically start moving towards a rally point I've already set.
A vassal limit (like the desmene limit, but more forgiving of going over) would help exacerbate the difficulty of managing a large kingdom (because I know it's quite possible to get a bunch of schemers under control with attention to vassal traits and a Gray Eminence ruler). I also want more intra-kingdom plots. Moving titles around and fabricating claims is all well and good, but what about de-legitimating someone's heir, or accusing a low-piety character of heresy? There's all sorts of fun backbiting I'm sure we could dream up.
I don't understand a few points in your message. Please could you explain?
For armies: you want to avoid clicks, and so suggere we have to click on each province? The two possibilities are acceptable: it may be more realistic to have to send messages to the levies, wait and then spend time reuniting them before to go to the battle. It's equally good idea to avoid clicks. But please explain how the two would be possible simultaneously.
For the vassal limit: something that may be interesting, but please give more explanations, so that we can have a better view of what you're suggesting.
For plots: it's true that sometimes I feel frustrated to don't have any available plot against a vassal or rival I can't stand. Then I would plot anything possible against him, just for the pleasure of it. And we can be confident when thinking this was also the case in true life in these times. From littles school yards to old people's home, from first written texts to now, it has obviously been linked to human nature. So yes, good ideas I think.
Last thing: you're posting in a thread where the OP said 'Ok, not bad, but let's do it from scratch'. Then everybody says 'Yay' or 'Nay'. But wo are you answering to? Are you a supporter for an hypothetical CK3? I just hope, with all ideas it seems you have, you would prefer to see them progressively implemented thanks to a few DLCs, permitting you to experiment all of this much sooner?
