Saw this a few days ago when was in CM.
The other Paladin was spamming Rage of Halone rather than using the typical Fast blade/Savage blade/RoH combo.

Does this generate greater enmity somehow?
At least from what I had observed, the enmity created was greater going through the entire combo, rather than just spamming RoH.

Perhaps I was mistaken?
I cannot find Kitru's post regarding Enmity generation per ability either.
