1. change villge claim occupy whole layers as follows L0, I mean(sorry about my bad english) if you just set village coords 100 100 ~ 0 0
then suitable coords of L1~L5 100 100 ~ 0 0 should be subordinated to ownvillage claim as well, so you only can build village authority objects only on ground
this will make sieg system more clear, and variable battles better and will motivate ppl to widening village claims. (if can't atleast from after world)
2. village authority 'wrestling'
when two village's claims are touched in 10tiles(or whatever) both village's authorities would be ran out untill one village absorbed or till 0 auths(so be destructable loosing one)
3. CR warp costs authority +(when one come from other village, arrive one would costs)
I suggested because they are reasonable. not quite sure how explain to you guys about their good and bad
