The Annihilator and Conqueror armor sets have been adjusted some:

High-Level Encounter and Armor Set Adjustments
 
Based on our observations and your feedback, we have determined that Fortress Lords and contested capital city guards are not providing the intended level of challenge. These enemies are among the most dangerous in the game, and battles against these deadly adversaries should be nothing short of epic.

As a result of the changes we've made, Fortress Lords and contested city guards will now be even more challenging that they were previously. In order to help players survive these perilous encounters, we have made the following adjustments to two of the game’s high-level armor sets.

• We have updated the Annihilator and Conqueror armor sets (acquired through a variety of high level RvR) to include Wards, in order to maintain parity with PvE Armor Sets.
• The Annihilator set now includes the same Ward as that offered by the Bastion Stair's Bloodlord set.
• The Conqueror set now includes the same Ward as that offered by the City Dungeon Sentinel set.
• Players who equip pieces from the Annihilator and Conqueror armor sets will be better-equipped to challenge the Fortress Lords and contested city guards. The more pieces equipped, the better defended players will be against these deadly adversaries.
