Breaking through the palisade of anyone active is hell.
First, you need an armed guard to watch the ball for 24 hours without sleeping. Good luck finding anyone who's willing to waste their entire day doing that. The ball can be taken down by naked alts and if they succeed, the guard will have to start over from the beginning. If you're trying to raid a village you might need several armed guards to avoid having one guy get gangbanged by a group of enemy warriors. If by some miracle you do manage to break through, the owner of the claim will have alt vaulted any worthwhile loot. A similar problem applies to battering rams. You need someone to guard them for 24 hours and they can be taken down relatively easily by anyone who's not a noob.
The biggest issue is that several layers of palisades is enough to turn any space into an impenetrable vault because no one wants to spend a week guarding balls or rams. Widely spaced layers also make battering rams impractical because they break down every 25 tiles.
Can you guys think of any solutions?
