Well, Ifrit is sort of a different beast, since it's single target. I'm extremely shocked if I have less than 200% enmity from the next highest person on Ifrit, simply because you can focus your efforts and keep up a good Skull Sunder rotation. I've always liked tanking single, large targets; and it's something I consider myself fairly proficient at. Large groups, on the other hand, is something I have very little experience with. So when a fair number of people appear, claiming that spamming Overpower is the way to go, and that is not even close to my own technique, I get a little worried.
