how about... nerfing 26k tricks, making PVP rewards less expensive when cashed in and harder to get, and GE price controls (although this will take a lot of thought on how to do without being abused by clans)
according to jagex's update news on mobilising armies, zanik's crossbow was also updated to fire more bolts. does anyone know what bolts this update includes? edit: i have confirmation that it wont fire broad bolts i have enchanted and poisoned bolt orders in the grand exchange, ill update them as they come in edit 2: zanik's crossbow WILL fire ENCHANTED and POISONED bolts!
