You have the title right there.Blizzard missed to set the Zandalari Infiltrator immune to controls so here is the bug/exploit.
You need a Priest for this of course, with the Dominate Mind Talent
I have tried to MC pretty much every other mob but without success so I think this is the only one.
If you want to save time you can find this pretty usefull especially if you have 2-3 priests that can mind control all the Infiltrators in the pack..killing each other etc.
