I'd like some info about the RvR rules but wasn't able to find any documentation about this.
What's the point of claiming keeps or resources, apart from the "fame"?
In DAOC for instance, IIRC I was informed when a guard was attacked.
In Darkfall (pre UW) I was being notified when a player entered a hamlet or similar.
Those two are just examples, before people start yelling "we don't want this", nowadays you have to spell everything out so someone doesn't assume too much
Do guild member receive any bonuses?
Is the keep or resource being repaired more quickly?
Does the guild receive other benefits, like part of the revenue generated from siege weapon and material sales?
