Cheating in Cyrodiil has gotten way out of hand. But as long as players can get away with their cheating they will continue. The problem is of course with the players who cheat but you also have to blame ZOS because they do nothing about it.
@ZOS_BrianWheeler the Z-axis fix for DK chains seems to have been reverted as I saw a DK use chains to pull himself up twice today at Arrius keep PS4 NA via the front door mage guards.
The visual was quite interesting as a couple of cast of chains actually went through the mage guard into the sky.
