Karu
I can: 1) stay in instanced location, like apartment, or mission giver rooms 2) stay by altar 3) use aura and hit teleport. Aura lasts for 18 seconds and teleportation takes 15 seconds. I would leave unharmed anyway.because you cant escape in 10seconds that takes to teleport out.
It also prevents pvp'er hopping around from hot-zone to hot-zone.
