Starting July 22 on all servers, we're going to reduce the number of ghost acres created by landgrabbing. Buildings taken will be multiplied by a factor known as "unreduced DR". Unreduced DR follows the same rules as normal DR but it cannot be canceled out with attacking. In addition, unreduced DR equals 0 instead of 0.1 for any hits after the first 12. The ghost acres generated by a NW difference between the attacker and defender are also multplied by "unreduced DR". The following are a few examples to illustrate the difference between the old and the new system.

13 hits in a row under the old system:
acres gained = 1.0 * (base acres + ghost acres)
acres gained = 1.0 * (base acres + ghost acres)
acres gained = 1.0 * (base acres + ghost acres)
acres gained = 0.8 * (base acres + ghost acres)
acres gained = 0.8 * (base acres + ghost acres)
acres gained = 0.5 * (base acres + ghost acres)
acres gained = 0.5 * (base acres + ghost acres)
acres gained = 0.35 * (base acres + ghost acres)
acres gained = 0.35 * (base acres + ghost acres)
acres gained = 0.15 * (base acres + ghost acres)
acres gained = 0.15 * (base acres + ghost acres)
acres gained = 0.15 * (base acres + ghost acres)
acres gained = 0.10 * (base acres + ghost acres)


13 hits in a row under the new system:
acres gained = 1.0 * (base acres + 1.0 * ghost acres)
acres gained = 1.0 * (base acres + 1.0 * ghost acres)
acres gained = 1.0 * (base acres + 1.0 * ghost acres)
acres gained = 0.8 * (base acres + 0.8 * ghost acres)
acres gained = 0.8 * (base acres + 0.8 * ghost acres)
acres gained = 0.5 * (base acres + 0.5 * ghost acres)
acres gained = 0.5 * (base acres + 0.5 * ghost acres)
acres gained = 0.35 * (base acres + 0.35 * ghost acres)
acres gained = 0.35 * (base acres + 0.35 * ghost acres)
acres gained = 0.15 * (base acres + 0.15 * ghost acres)
acres gained = 0.15 * (base acres + 0.15 * ghost acres)
acres gained = 0.15 * (base acres + 0.15 * ghost acres)
acres gained = 0.10 * (base acres + 0.0 * ghost acres)


13 hits in a row under the old system where the attacker and defender take turns grabbing each other to cancel out the DR:
acres gained = 1.0 * (base acres + ghost acres)
acres gained = 1.0 * (base acres + ghost acres)
acres gained = 1.0 * (base acres + ghost acres)
acres gained = 1.0 * (base acres + ghost acres)
acres gained = 1.0 * (base acres + ghost acres)
acres gained = 1.0 * (base acres + ghost acres)
acres gained = 1.0 * (base acres + ghost acres)
acres gained = 1.0 * (base acres + ghost acres)
acres gained = 1.0 * (base acres + ghost acres)
acres gained = 1.0 * (base acres + ghost acres)
acres gained = 1.0 * (base acres + ghost acres)
acres gained = 1.0 * (base acres + ghost acres)
acres gained = 1.0 * (base acres + ghost acres)


13 hits in a row under the new system where the attacker and defender take turns grabbing each other to cancel out the DR:
acres gained = 1.0 * (base acres + 1.0 * ghost acres)
acres gained = 1.0 * (base acres + 1.0 * ghost acres)
acres gained = 1.0 * (base acres + 1.0 * ghost acres)
acres gained = 1.0 * (base acres + 0.8 * ghost acres)
acres gained = 1.0 * (base acres + 0.8 * ghost acres)
acres gained = 1.0 * (base acres + 0.5 * ghost acres)
acres gained = 1.0 * (base acres + 0.5 * ghost acres)
acres gained = 1.0 * (base acres + 0.35 * ghost acres)
acres gained = 1.0 * (base acres + 0.35 * ghost acres)
acres gained = 1.0 * (base acres + 0.15 * ghost acres)
acres gained = 1.0 * (base acres + 0.15 * ghost acres)
acres gained = 1.0 * (base acres + 0.15 * ghost acres)
acres gained = 1.0 * (base acres + 0.0 * ghost acres)


As you can see, the amount of ghost acres generated is greatly reduced in both cases. We hope that these formulae changes will have positive effects on the game but will monitor each server to see if any further adjustments are needed.

In addition, there was a small bug related to the calculation of DR that will be fixed. This bug fix will not affect most players.
