Stealth Detection Reduced or Removed on Many Items
Blizzard has reduced or removed stealth detection on a number of items because the team "felt these items provided a necessary advantage in competitive PVP and forced players to use lower level equipment even when more powerful items were available to them." The changes are already live and the tooltips will be be updated to reflect the changes in the next minor content patch.
Ultra-Spectropic Detection Goggles can no longer be used in the Arena, and all epic engineering goggles have had their stealth detection abilities removed. A full list of items that have had their stealth detection reduced can be found after the jump.
