theres this hacking system,called WoWEmuHacker,its helped me alot on private servers,but ive yet to test it on live because i didnt want to risk my account.
Heres a list of things you can do on it:
Wallclimb-lets u climb on most any walls
Fall damage-takes off damage from falling
Teleport to plane-not sure what it does
No Clip-the basic noclip for any game (lets u fly around and go thru walls)
P to P Teleport-havent tryed this yet
Flymode-lets you fly
Levitate-just like the priest power levitate that req. a light feather
Normal Mode-i guess that makes no hacks affect you
Speedhack-runs faster,and theres different speeds,Aspect of cheetah speed,wisp speed,Epic mount speed,griffion speed (i guess this is FP speeds) and theres mach 10,the fastest of em all
Tracking types for all mobs and herbs/minerals/treasures
Corpse and Spirit healer teleport,
teleports using xyz coords
a current location coord finder
a list of teleport places such as cap citys,gm island etc
and Gravity modification
