This is exactly the reason why I shun melees for BRD/BLM. I've never had a melee actually equip a bunch of enmity abilities to try and grab hate on the one moogle we're focusing on. Perhaps that's more of an issue with sub-par melee(s).
As far as kill order goes...
It's my understanding that the King copies an ability from the last Moogle you kill (or does he just use it more frequently?), so that is why there are specific kill orders. Once you get in the middle of the kill list, it's more a matter of preference which you kill, as opposed to something super important. The last time I was in a PUG for this, the people could not fathom why you would kill the King 2nd to last, instead of last, so they killed the WAR before the King. Then we spent a good 5 minutes trying to stay alive while the King wrecked us with the WAR AOE. We won, but it was ugly.
