Well I like to think that when I run DF WP, I never do "speed runs" but I DO do fast runs. As in, I group up certain mobs together when I know there is enough aoe and the healer can handle (usually 2 packs at most etc). My groups almost never wipe and even on the occasional time we do we still finish the dungeon in about 20 minutes pretty comfortably. I do however raise an eyebrow if I pull a small group and the blm decides to single target them one at a time and never use flare. Makes life harder for the healer and for the tank.
