Same concept with the castle, but insteas are 'forts', each with the same type of bank. Scattered throughout the wildy contains rare resource spawns such as prime fishing spots, addy and rune ores, trees, caged up mobs with good drops, quick skillup agility courses, a giant furnace to smelt ores with extra procs, etc.
These are captured by teams.
Entrance to the forts are enforced by a "pay bank", where you deposit a certain amount of gold and in turn are granted access.
To capture a fort, all you need to do is be the team that has the most players around it for a certain time period..?(or some other weird rule to ensure the team that captures it needs to work to secure it actively, ensuring it can flip sides easily if a team doesnt work on keeping it).
Players trying to access the forts immediatly get unskulled and are not succeptable to attack, and also cannot try and capture the fort.
~~ Just a suggestion to add some logistics and group play overall ~~
