How do focus macros work exactly? I ask because with im 3boxing with my shaman(s), ill notice that if I rapidly switch to a different target and start shooting off lightning bolts, or if I just rapidly choose a target and start firing, that my clones will not attack my target. They will instead attack the previous target I had or what seems to be the closest target that they could find (I say this because this happened today when I did not recall targeting a specific mob, yet my clones attacked it).
