Stop contributing to the Mage Tower when its within 3 days of server rest and Nether Disrupter is under construction.

If you get the Nether disrupter world boss up at a time when it carries through the server reset on monday/tuesday you can get loot off that boss twice. Thats 900 base ilvl gear that you can reroll on, which is better than herioc NH gear, and as good as the first 3 bosses of mythic NH.
