War flags no longer require being in a realm at all to build, and the builder can choose to build the flag to expand any of the neighboring realms to the attacked tile.
The cooldown of building a war flag is removed.
A challenge cooldown of a day or so tied to the challenger's village would be ideal, but I don't think you can differentiate dummy villages so it seems like a waste of time. No or limited cooldowns would be fine as long as the character doing the challenging is at risk and not a vandal alt.
A one day "protection" period is added to a any freshly claimed thingwall, preventing new war flags from being built.
A newly claimed thingwall cannot be used to further extent the realm during the "protection" period. Similar rules to building village banners.
War flag material cost reduced to be trivial. Maybe five ropes and some blocks.
War flags should have like 10 soak minimum to prevent fresh alts from slapping flags.
The war flag retains the same grace-no-bashy period dealy as now, except the grace period is only 10-20 minutes, even with guarded marches, and the active period is 10 minutes.
The warflag disintegrates if the person who built it leaves the region, or some other mechanic to prevent people from just hail-mary building flags 24/7.
War flags can only be built by characters with developed skulls, or ideally the top 20-30% strongest characters if you wanna make a cool needlessly complex function. Enough to exclude vandal alts, but be inclusive for average players, ideally.
Everybody inside BOTH the attacking and defending realm's borders is alerted whenever a war flag is built, including the thingwall name, and MAYBE the skull name of the person who built it.
Building a war flag is ALWAYS leave a scent of some kind.
The realm buffs icon displays how many thingwalls are in the realm.
No claims OR building within render distance of thingwalls to prevent autism.
Let people build milestones & roads like within render, tho.
Move the thingwalls away from water to prevent gay ass cancer boat fights. Give them a road that (like paved path, not milestones) that extends from the thingwall to the nearest water. The road has the same claim & building protection as the thingwall.
IDEALLY a mechanic added to find thingwalls easily, like them appearing on the map whenever you enter their region, or a quest given to see it with an arrow whenever that quest is selected.
