I think capping battle camps should require at the very least, 20fs, similar to many other features of chaos/epic including capping hota pillars. The reason being, if there's a battle camp in a spot that could in any way be dangerous, someone can run up an alt, with under 20fs, and cap the battle camp, and any retaliation from another kingdom will gain nothing from that. Especially if the battle camp is near a deed and said alt can just repeatedly spawn and run back to cap it, while the main account can just sit barely in local and gain rank from the alt capping the camp.
