I did not find myself thinking much with respect to this zone. I traveled here more than usual, with quests sending me around as I presumably missed the wave of perfect ordering. That led to running around the zone, into Shattrath, and occasionally elsewhere. Other times, I got to an area and stayed there a while. Instead of one big quest hub, quests were widely spread here, with one medium hub and chains all over.
My first thought upon entry was “the forest of parsley.” You start to ignore what the trees look like. About half way through, it converts to the land of the dead, and you spend your time in the south amongst the spirits. As a Paladin, I always approve of that. The difference between the two halves was so large that I forgot for a while that both were part of the same zone.
I just do not have many comments on the zone, despite doing every quest, getting a couple of levels, and getting the achievements. The many scattered quests, for several different groups and in many sub-zones, kept me from getting a single, overall impression. I think this worked better with the many small areas in the Hellfire Peninsula because they felt more tied together. Having fewer hubs helped unify the experience. It does, however, give you an idea of the many factions at work in the expansion pack, becoming a messy web in Shattrath and its larger zone.
There were a few new models, but the zone was dominated by humanoids, which are known quantities. The PvP quest for the zone has the unfortunate feature of shutting itself off for hours at a time after being done. Yes, that makes the reward more meaningful, but it also means that I could go through my entire play session without having a chance to affect it. I note that there is a four-winged instance in the zone. I heard people running Mana-Tombs (no, my Pally is not healing a PUG tonight, thanks), but otherwise good luck visiting the rest in a post-BC world.
