"Epic"

After understanding that getting the questing achievement in Zul'Drak is impossible without group quests, I moved on to the Storm Peaks. The realm of powerful elementals, the dastardly iron dwarves andd the majestic giants..

..who ask me to participate in a snowball fight. Using a giant. Against mobs that I can kill faster myself.

But aside from the usual problems of low respawn and drop rates, running back-and-forth, the zone isn't that bad. It's the first one designed for flying mounts and it even uses phasing reasonably. For example, there is a big iron dwarf golem that's being constructed. It's a landmark for a series of quests, and eventually the iron dwarves manage to activate it. The mandatory faction grind with Sons of Hodir uses phasing as well.. and most of the time the reputation grinders are safely hidden away and won't tag any quest mobs. Of course, not every designer got the memo about this new, exciting feature, but it's not like Blizzard's famous for their consistent quality or anything.
