Just make bearers a must for harvesting or raiding.
Improve ai for castle defence.
Make farming more fun. Like have a world boss garding a big supply of materials. Like the spider hordes gossamer or the brimstone lake boss guards a huge supply of brimstone.
It would be more fun bumping into enemies fighting over materials to build/raid.
If the changed the purge back and had named thralls only come on purges it would encourage players to build sensibly to get the benefits of named thralls through a purge.
Not a box up a mountain.
I think trebs are cool but when people can carry sooo much explosives in one go its too powerful.
Remove encumbrance perks. Make bearers a must for raiding. It would make it much more realistic. Or introduce a cart or wagon for the horse. To carry supplies. But only like 10 demon jars at once. Atleast then you could maybe spot someone showing up and stocking jars on a treb.
I just think its easily made more fun that way
