We can have no battles, or we can choose to have battles. I rather we members of organisations decide how to move forward.
Each Org and choose their own path, and each citizen can choose their own path. I see nothing wrong with allowing the option of PVP, and at the same time, allow a truce that will not have PVP.
We as humans will always have the urge to battle, and to prosper. There will never be a utopia.
