So we have discussed many things, and it is clear that J+L do not want bots. Fine.
There are alternative defenses. The fact is, people sleep, people need to sleep, hell, this may be a shock but I'll go with it.. People have fucking lives outside the game. This should not mean that their crap be entirely vulnerable.
Raiders also have the advantage when people are active anyhow, as they not only know in advance that they are attacking, but they also have numbers on their side, while a town may have only a fraction of the same amount online at the same time - The recent WV raid is proof of this very HUGE flaw.
So I propose a few changes that may help.
Village claims, if someone enters and turns criminal acts on, they should receive a debuff of 50% on all of their abilities and attributes, another black skill "Sinister Intent" would lower this disadvantage to 25%, while certain equipment can bring it as low as 10%. However, If they are a member of a village, they can use village authority to remove this disadvantage entirely. It would last 3 real life hours.
Another suggestion is guard towers. They require obscene resources to build, do not have a large range, and when built, require food, arrows, and water to function. These towers would not be particularly strong, but would provide a distinct tactical advantage. However they would only fire at people who are not members of the village who have left scents within the village claim.
