Currently when you place a claim, everyone can destroy it and unless you have rage there's no mean for you to defend it except for shoving. I think there should be a debuff that's applied on the person attacking the inactive claim that allows claim owner (and their party) to attack the perpetrator without having rage skill. This way early game will be more interesting because it will now be possible to contest for the valuable areas (as if... making a CLAIM to it) and force both parties to make impactful decisions. Since injuries in this game are usually debilitating, when presented with a new claim, an already existing owner of the nearby area must decide whether they're willing to risk injuries that can potentially hinder their progression and engage in a violent confrontation or explore other means of pushing unwanted neighbors out like threatening, bribing, waiting for a window when their entire party is offline in order to break their claim or simply letting them be.
To better illustrate my point, please consider the graph below:
