We all know that PvP is on, so i'm guessing more citys are gonna get into battles, i have come up with some rules that i think all players should follow by when in a war.
-people can greif, steal, and attack enemy citys.
-Admins can not help citys with wars, they can take part, but may only spawn iron and lower items, unless given diamond items from the city.
-all players part of a city in a war, must have PvP enable so they can get attacked.
-any players that don't want to take part in the war have the right to leave the town
-anything thing is allowed from tnt to swords to clay to yo mighty fist
-If an enemy town wants to surrender you claim their town and get all the money from that towns bank
-all antigrief saftey commands for the city must be turned off so that enemys can attack and destroy their town.
-if anyone not from an enemy town griefs they still get banned.
-if a town breaks one of these rules, they automaticly have to surrender and hand over their town.
-if 4 or more towns want to go to war with a town that doesn't want to, the town is forced to because there must be a reason they want to go to war with you.
These rules only applie if they both agree on war with an admin in a server to witness them agreeing. If two towns agree on adding or changing a rule. they can as long as they agree.
The reason people can grief/ destroy enemy towns is because it what war do you not try to take over the enemy's town? you don't just hunt out they enemy people, you go attack the core enemy, the town.
These are the general rules i have come up with, post more rules or ideas or things you think i should change.
