I just found how buggy is to sheep people falling down in the air.
I think this is useless, but anyways this is all you need: mage who can sheep, area where you can duel(or horde, like i had as a alliance) and of course, the target.
This is how it goes:
Mage starts to sheep that target just jumps off from cliff.
This is what happens:
Tough sometimes that sheep falls and when its going to crash at ground it flies back to place where it should've been.
Not sure can you find it useful, but atleast i had fun with it.
