While ganking lower levels in moonglade i found that the guards have a bridge phobia, so the guards will not attack if you are on a bridge at the start of attack... however if you try to pull guards onto it they will attack, and sometimes evade and still attack, if you want to kite thte guards get in the water about 2 meters out, where it is quite deep and they will run back.6):
