There is a place NE of Icecrown Citadel in Icecrown, that has a bunch of Skeletal Runesmiths and Umbral Brutes. The Brutes have a knockback and I think the skellies have a sunder-like ability, but other than that they are all melee. There is a path going up to the ledge where there are no mobs, so you can land there safely every time.
What I did was put on all my block rating gear (not even close to passive uncrush anymore) including Figurine, which is still OP, mounted with Crusader, and rounded up all mobs. There is a big vase in the NE corner of the platform. Run behind it from the left and you find a place where you can wedge yourself and not get knocked back. Moreover, all mobs will be in your frontal cone. SoL/JoL, use Holy wrath liberally, and use Figurine. I did it crittable, which could be slightly scary a times, but I was able to do a pull every 3 minutes. Each pull was 16K or so XP unrested, which worked out to be ~1% at level 79. At level 79 that is 320K XP/hour. In getting from 45% to 80 I made a couple hundred golds and got ~260 frostweave cloth in less than 3 hours.
