Battlefields should remain there for a lot longer. Even if it took an in game month for a battlefield to disappear, you'd probably find 1 to 2 battlefields in a beeline from one end of calradia to the other. However, Battlefields would be picked clean in days, as everyone would know of an epic battle between factions. A group of peasants from nearby cities and villages would head straight for the battlefield in this case, because they know it happened, and there would be precious equipment left behind. However, groups should have the default 'take the essentials' as the above post said, so it would take maybe 4 different groups to pick a battlefield clean. If farmers loot a batttlefield and manage to get back to their village, that should affect the village in some way. Maybe being able to repel bandits as the men have some weapons and armor. Peasants and bandits are pretty much equal. Peasants might be better off, because they work constantly for years, and usually have lots of muscles. Bandits sit around and drink waiting for targets.
