I was thinking that if in haven and hearth, in addition to the curiosity system, some sort of Local leadership level distribution of LP was made available.
Basically an established village makes LP.
The more sacrifices made at the altars, Refined goods produced and then sacrificed, The number of structures in use within the town's borders, It all makes LP. Which is up to village leadership to decide on distribution. Basically that random guy, let's call him "dingus" gets more LP because he's online often, and we need a guard. The leaders are trusted to distribute this LP fairly and impeached if they fail to.
It allows players who play more, and produce more useful things (the surplus of which is sacrificed to the ancestors) to contribute not to their own leveling but that of the civilization or tribe they are part of. However this makes it likely that a group might put all it's effort into training up one invincible badass.
Why not? cultures produce epic heroes all the time.
Max LP gain (for a given settlement) could be capped by the average LP of all the citizens, thus preventing Alt spamming. You're not rewarded for pointless tasks, your village is rewarded for you actually contributing to the economic machine of your village.
Keep the curiosities as well of course. But just make it seem like when I play, I'm actually doing something useful I guess.
Back in world 3 I had a guy in my village. He was an unstoppable murder machine. I would walk into the woods, cut down trees, stump them out, plant new ones and stack the logs so he could bucket with them. Later on I went a little crazy with mining. I felt like I was doing more for my village pumping our primary guard up than I did when I was acquiring buttloads of ore. Once we had tons of metal saws, we gave nary a damn.
So as for sacrifices and handling distribution, every day the ancestors would demand a thing. For the whole day, the entire world economy would switch to acquiring that thing. It could be any highly refined item, or even a simple low level foragable. But we would all gather it, and then at two specific times (6pm and 6am?) it could be offered to the ancestors to grant that village LP, based on it's total members and how much of it they produced. It would encourage diversity and specialization, contradictory terms I know. But everyone would attempt to be a little useful at any one thing that came up, and super useful at their one specific thing so when their day to shine came along, oh boy could they shine.
This would also prevent nations from stockpiling too much wealth, Who cares if you have 10000 steel stockpiled if you plan to burn most of it for the honor of the dead?
Can you afford to trade that steel? You may need it for when that magic day comes up. smaller groups would, naturally make less LP and have less to go around, but founding a new or splinter settlement is hard. Established nations usually end up in charge.
This idea is horrible and rough around the edges.
