I also did the kite strategy. Just make sure the kite-er doesn't get slept or incapacitated in any way, and you are golden. It doesn't matter if they're a tank or a WHM. We've used both. This fight is actually REALLY easy when compared to most of the job final battles that I have helped with. Some final quests require, hands-down, a party of eight people. I believe we did this one with 5... and it was easy. I know another group that trio'd it.
