1. Add more events like the Arcanite Fields event so players will all farm to create guild furniture items. People enjoy this event where you contribute to something and its more entertaining.
2. Add a mini event where players decorate their houses for a certain theme of the event. So players will be interested to decorate their houses or make an lb event for the best decorated house.
3. Add a craftable item for the guild hall that can make a pvp area inside the guild hall.

Let me know if the idea is bad or good.
Cheers!
