Well....
About fastening the year, we can see: different opinions. If that is s.th. to change it should be with sliders, like flesson suggested, I guess. Just keep in mind it would be more of just adjusting the aging, I strongly assume that there is more to it and has impact to many things.
I do respect that people compare to CK3 on the one hand, on the other, well, I personally cannot see why. Bannerlord just is not CK3.
Personally, I am happy it is not. Bannerlord is quicker to adapt and easier to play. But that is my personal style and I totally respect other opinions, just, Bannerlord is not CK3 and also it does not claim to be.
Honestly, I like the way bannerlord does the dynasty thing, it is not really setting up a dynasty, but therefore it also is not that stressy.
I do agree though, and again it is all personal and my opinion, a bit more on the diplomacy side wouldn't hurt, like peace agreements and maybe trade agreements... we've seen those on warband, but it were mods. But it will have influence on balance and such heavily, so it is not done just like nothing. Remember on warband, the diplomacy mod also was in dev for years. Even within the mod, people complained, because you never can have everybody satisfied.
I'd be fine having it as DLC, not necc. in the base game.
As for the patch, I personally think, it was anounced for november, which we are in the middle of it now. Forgive me, no offense here, but I dobt it helps to complain before that goal is not achieved. Again, my personal point of view, just my opinion.
This said, all these things are optinions. And from those we have many, some of them just do not work well together. That's just like it is, I guess.
For the core mechanics of the game, there are still flaws enough and I still like to believe ( and see it slowly) that they are being worked on, like caravans and workshops that are not really working, well, I'd say, as intended.
