Hmm...been toying with this for a few minutes on my shamen and so far it seems to work...haven't tried with one or more of them dead yet(but horde're being quite brave today and ganking in town so I might be able to shortly lol) but so far it's been seamless targeting...the only complaint I have is that when I have no target, it targets myself...not really an issue yet but it could be an annoyance :p
