In the old days we used to Burn the corn to destroy excess supply controlled by the elites.
Remove 50% of rune items in game banks and characters. Remove 75% of all gp from accounts under a shared IP. Ban all character who attempt to evade the tax thru VPN. Remove 60% of all rares for shared IPs. Single characters under the same IP with only 1 of that rare will not lose item. Remove 90% of all resources and runes.
Desperate times call for desperate measures Burn the corn and get the economy going again
In like 2012 I played a server that tried this and it died shortly afterwards. And that's a server that at high points had 200-300 online with at least 150 unique IP's The pking was epic with lots of 1v1 opportunity at and below castle.
But they tried to fix the economy and fukt it all up. Won't help here either.
