Not sure if this can be of any other use than to irritate, but I doubt it's intended so I'll post it anyway.
As a Death Knight you can cancel someones noodle cart by dropping your AMZ ontop of them. Guessing it has something to do with the noodle cart buff not stacking with the amz buff and therefor the older buff (noodle cart) gets canceled.
Havn't tested if other similar spells have the same effect (smoke bomb, PW:Barrier, spirit-link totem).
Step-by-step:
1. Be a dk
2. Spec AMZ
3. Find a victim, someone using a noodle cart.
4. Place AMZ ontop of your vicitm.
