Right now sieging a village isn't very rewarding and usually leads to a frustration after everything is being alt vaulted and sometimes even causes total destruction of the base that is being sieged. In my experience every place that i've participated in sieging was abandoned and people who played in it either quit or moved into another village. The time it usually takes to bring shields down is 14 hours, now if people start using new mechanics to fix the shield with brimstones it will take 3 more hours to destroy claim or village shield. Now imagine that there are whole bunch of personal claims inside the village, outside of the outerwall's range, so that raiders would have to spend extra 14-17 hours to raid the personal claims just to find out that everything that was in the claim would be moved to another claim that has full shield. With this mechanic sieging isn't really worth the effort if people under the siege know that they are doing and prepare in advance.
I think shields on personal claims should go down with the village shield even if they aren't being catapulted or rammed, as long as they touch village claim and claim village shield goes down, personal claim shields should go down as well.
I also think that alt vaulting should be nerfed by making hearthfires lootable, and add physical vaults to the game, similar to the ones that were in the legacy, containers with soak and keys, and finally add another village building (similar rule as for charterstone) that can only be built once per village, that will have a huge soak and keys, aka Bank of Nikolai (https://www.youtube.com/watch?v=0o8XMlL8rqY). edit: Make it unable to use any sort of teleportation mechanics while inside the Bank of Nikolai, and when its hp goes down to 25%, make it possible to enter without the keys, and have similar eyeball mechanics before u commit entrance as to when you teleport via crossroads. (also hoping that new mechanic that doesn't let you repair things that are being destroyed works for houses)
one more idea on sieging, a little bit off topic - add some sort of reward in form of objectives when you siege a village, that would let you gain fame points if you successfully siege or defend your city, and make them usable similar to numens in legacy, but more pvp oriented maybe?
