Your reading comprehension is poor. Yes the mod puts you in an unbalanced situation. That's clear as rain throughout the thread from my comments.
The vanilla game isn't unbalanced. But Bannerlord supports mods! I'm not modding myself (except them .xml-files), so I don't know what modders can do, but Taleworlds could, and in my opinion should, ponder the case of unbalanced campaign starts with mods. It's not hard.
Dear goodness, I do not know at this point how to make you realize how ridiculous what you suggest is. Nothing seems to work on you my friend.
The game does not support mods. It allows them. I enables them. It makes it easy to create and use them. But that's it. Whatever mod you install, it's entirely on the modder who created it and on you, who are using it. TW has absolutely no reason to add functions into the base game that will make particular mods balanced. How hard is this simple FACT to understand?
It is 100% on the modder to make his mod balanced. If he won't, or can't, then it's the problem with the mod itself, not the game. Thus, TW has absolutely no reason to do anything to make the mod balanced. Do you finally understand?
Also, there are thousands of mods, and if we were to go by your logic, TW should make sure that each and every one of them can work well. Because why should they stop on a mod that adds different starting conditions? There's nothing that makes that particular mod special in any way. Do you realize that this is literally impossible to do? It's not difficult, it's
impossible.
Or do you think that TW should bend over backwards just so that a mod that YOU use works well? Are you that self-centered to demand something like that? I don't want to think that you are.
