The quest
"Bringing down the iron Thane" where you take control of a Charged War Golem is bugged so where you can PVP while in control of the Golem only 1 ability to use but just spam the heck out of it....
I've had a lot of fun with 34k hp and increased run speed chasing down unsuspecting alliance. Most of them will think you are just an NPC at first, If you get low hp just get out of it and use the Controller again to hop right back into a full hp Golem.
Have fun.
