It seem to me one odd consequence of these changings is that sieging is not tied to any particular personal/village claim nor siege object. For example:
Forgive crude image. Brown box is palisade, red box is siege claim. Maroon X is siege machine generating claim. Green box shows village claim being sieged, blue box shows personal claim attacker builds as forward base. In this case, attacker sieging enemy base is also building up authority for defender to attack his forward base. Similarly, if defender tries to counterattack this forward base, he will build up authority for the siege claim which is threatening him. Does this not prevent counterattacking? To root out forward base is to root out your own base as well.
Generally, it seem impossible to attack any thing which is claimed within 49 tile of your wall, because as soon as you will gain maximum authority, these men can come and break your wall too.
Do I miss some interaction here?
