Imho proper defence (hard to destroy) right now is designed for communistic groups, so they can spam basic walls around their small camps.
Salem was designed to give players freedom, so I want to use this "freedom" in more capitalistic way, but to do that I can't have tiny camp, capitalistic towns need space and that space can't be filled with spammed walls in 50%, that would be just stupid.
Imho "proper defence" should be expensive and building it should be time and resource consuming, but that does not equal to spam as many as you can weak and cheap walls like we can see right now.
I am suggesting to boost town claims, so braziers put into personal and town claim would fire on first vandal attempt not second.
That should make town scroll worth of 2500 silver for many people:)
