I still want to meet these magical healers that can out dps an equally geared WAR (I'll even throw DRK in there) in dps stance on a boss to make the dungeon "faster".

Sorry. Cleric stancing it with a VIT tank isn't beating a str geared/dps stance tank. Thus, fights are faster with me in my str gear. (Leave PLD out of this, they got shafted in the dps department.)

Trash, sure. Go vit. Trash dies quick anyway, provided your dps are not derps.
