[Rogue] Blind people off the boat

Ok well i was running my level 10 friend from teledressil>westfall and we were waiting on the boat for it to leave, right before the boat started to pull out he dueled me and i blinded him right as the boat started moving, he fell through the boat and landed in the water, i have tried this about 5 times with him and it worked on all tries, it allso works alliance>horde ive only tested this on the draenie boat and the nelf boat.


EDIT: ive been doing this for about 40 minutes now i i have mastered it so that who ever i blind through will then die from fatigue
