Ok, let me say that in other words. Lets compare the numbers. As said before, Shield Oathed, 100str, 100det, 100crit, 30weapon damage PLD does:

63.686006592 Fast
267.48122768 Savage
551.94539056 RoH
265.3583608 Flash

enmity.

For Defiance MRD:

59,70563118 Heavy Swing
238,8225247 Skull sunder
557,2525577 Butcher's Block

MRD will do 855,78 enmity in 7,5 second rotation and PLD will do 883,1126248. Add the Maim which can be maintained 100% of the fight (that's why we can count it in (unlike FoF)) MRD will do: 1026,93 enmity.

1T MRD is doing roughly 15% more enmity.
AoE wise there is nothing to compere as MRD just destroys PLD in this matter.

My question is - ain't this seems a little odd that MRD is superior to PLD in 1t and AoE situations? And in what situation PLD fits better than MRD?
