-get rid of walls
-make houses lockable
-make player controlled animals invulnurable
The reason walls are such a problem, is you can't deal with thieves, they simply make a vault, and they are invincible. Plus, thieving, vandalizing shouldn't only be to destroy noob settlements that don't have walls. People should have to think twice before turning on criminal acts, because they'll have real consequences for it, instead of hiding behind a vault. I stopped playing because there's no reason to leave my walls ever, and that got boring.
Make animals unkillable/unstealable - the logic for this is, since everyone and their grandma has a brickwall, the animals inside walls are unkillable, and with walls removed, it would be silly to make cows thievable/killable by other players. How would you ever increase quality, they'd be killed in an instant by other players.
I doubt jorb/loftar would ever read a post in critique and ideas, but if someone else does, and happens to talk to jorbtar, tell them this idea, because walls ruin the game.
