Last match I participated in, I witnessed two instances of third-party tool use:

a) Unable to attack a Flames WHM standing directly in front of me. They were frozen and made no attempt to move until we retreated, at which point they magically came back to life again. The attack would begin, but stop partway through then "Unable to use that action at this time" (no, I wasn't stunned, pacified, slept etc.)

b) One Flames PLD was using a speedhack. He was bound and we rode away on mounts, only for him to not just *catch up* but dismount, Shield Lob and commence fighting us. The time it takes to Purify / Tempered Will, mount then move, we would be out of range.

If I see this behaviour again I shall be looking up character names on servers and filing a GM report. Whether SE take any notice or not, I don't care. I am completely sick of the cheating lately.
