The US Servers will come down on July 12, 2012, at 7:00 am PDT for a hotfix. The expected downtime is one hour. Here's the update notes:
POPULATION / ZONE PROGRESSION
Plane of War x4 Raid
- Commander Goreslaughter and Corpsemaul – The Toll of War curse that each commander casts will not have any variance to its timing. The curse will show preference to non fighters who are within a reasonable distance of the commander who is casting. If no non fighter targets are available, fighters may still be cursed.
- Hexapola should now drop more than one item when killed.
