don't know if I had ever seen this thread before, but from what OP considers "fixes" I gather it strays very far from what I see as a "basic wants" for the game.
Castles, for instance, remain mostly useless - they are what we call in my country a "white elephant" (consumes much more than it gives back - and as time goes by it ends up becoming a financial blackhole) One way would be to give every castle a village that produces something that goes a touch close to what town taxes can provide, but to do so hearths would have to have a much more impactful effect over village production rates. - RBM does plenty of "fkery" with a lot of mechanics by collateral (not sure if raptor has paid attention to that), as such it showed me plenty of possibilities if these things were done correctly, in RBM they become a major nuissance because the game isn't balanced to support his modifications which brings a plethora of campaign issues (for a mod supposedly dealing with battles, it over-extends A LOT). - one of which are horse producing villages - since he did some major fkery with their prices, horse villages can actually flip up to 8k per day in denars... (broken, I know) but let's suppose that we had villages that indeed produce useful equipment that has much higher costs, balanced properly, we could own villages that fluctuate between 500 up to whooping 3k a day depending on the produce, hearths and how often villagers completed their trade trips. Great and all, but also not as perfect as it should - the added layer would require (to be really good) that we had access to some sort of automation of boring and time consuming tasks, like having patrols - this demands either leader free "manhuter-eske" parties (could push companions, but with the vanilla limitation of how many we can get it would suck) that patrol or escort villagers on demand - or - give full control of clan owned parties with options in those lines. Vanilla BL goes too far in losing any realistic logical sense when it comes to management - we are arbitrarily limited to such an extent that we might as well just conquer a town and sit in it on AFK mode forever... So far we can only really intervine directly, but are not allowed to put brain-power into anything in the game - sure, campaign ai should need severe tweaking and access to the same tools first yet considering how the whole patching and feature 15th party balls for the game happened in the past 2 years, we can't count on TW for any...
As I've said, game has been slowly improving (slower than a drunken turtle skating on snails), yet it isn't going on any good direction so far, when it gets less disjointed, than I can properly judge again, as is it's in the same state as it were on release date regarding game design quality. Calling some half-arsed bandaids "fixes" isn't something I can condone with neither.
