Well I am in Warlords Acer and to be honest I think everyone will tell you to shut up. We Warlords will only conquer you if you are inactive. Thus not logging on for 2 days or more or a sim player or not being active on the forum.
I am in ownage but work with warlords all the time and know how they work and I agree with crazyduck. If you are not helping the alliance then you will be kicked and probably conquered. You actually help somebody else in the alliance this way.
