Is it an acceptable new-to-70 Item set? Is it worth the time to get them made? It looks OK for Holy, but don't know if they will be outpaced the second I step into a heroic/raid.
Although you have to keep in mind drop rates, frequency of your PvP, etc.. BOE crafted pieces from the AH may very well last you a long while, or they could get replaced on your first trip to a Heroic. It's a gamble.
if the khorium set is all you can get go ahead i guess. but for healing, most of it can be replaced in regular level 70 instances... or with items in easy heroics (SP) with fairly decent drop rates... i personally wouldn't spend the money on them. theres a holy pally guide here with some good gear advice.
