One thing I still find funny is that Holmgang is like the WAR's Tempered Will, except it works better. After trying and failing once on PLD, I found that Tempered Will which says prevents Knockbacks, doesn't at all for a Landslide. In Extreme the other day, I had the adds and because of my mistake on positioning one of them, I got some sludge on me and couldn't move out of the way of the other's Landslide. Good news though, was that Holmgang was up. It may not hold the mobs in place most of the time, but it sure did for me. Popped it, ate the Landslide with barely 1K damage, and prevented a full wipe from happening because of a mistake on my part because I was glued in place.

Someone suggested somewhere that it should drain HP from the target it's attached to, I think something like that could make it worthwhile, because the Bind in place can be a savior and a mistake depending on where you use it, I don't think that part of it should be taken out.
