It's not easy to please anyone as a developer. There are products I have followed for multiple years that are pretty ambitious that still see a long list of complaints. Particularly acknowledging and ignoring bugs for years on end. They address those bugs, that's pretty important. Maybe the economy changes were made so soon because they saw how easy on YT for instance, you can realistically breeze through the game with lots of cash. Maybe they think it will help people be more patient. Maybe it's just to give them some sort of baseline so they can further tune the other game if they are adding other features that work based on economic conditions. Don't know, just throwing that out there.
I think no matter what order things are done, people are going to have their expectations shattered. Like, I expected a finished game after patch day 1. */s* Seriously, I've never played a Bannerlord-ish title. My husband and our buddies were excited for EA. I saw husband play, it looked fun, so I picked it up. Yeah we poke fun at some of the bugs and some of the odd glitches (The back and forth "Family Fued" between the same two people), but other than that, we've enjoyed it.
I actually made a spreadsheet through my first play-through to give a crude idea for myself and friends of general prices so I could buy low, sell high. It also helped to pick up the map relatively quickly since I had almost no knowledge of prior lore/general geography.
