I propose to remove the 3 stones on the secondarys maps, and remplance only for 1 stronger. So, this will concentrate the PK when the enemy it's invading.
This gona bring Bigs Pk around the main stone until you need to switch to next map

The stones are to weak currently, there are a lot of damage in the server, and the blaster are already full 200TT + full distant. It's has ben converted on a "RUSH WAR".
