it was mentioned earlier, but feign death is a critically useful spell for hunters...even though it won't actually fool anyone (unless the other player is a retard), it drops aggro in pve (my guild is currently working on the vael encounter in bwl, and staying low on the hate list makes our hunters very happy), and allows hunters to drop from combat and lay traps in pvp. toss in the utility you get from it while pulling in the core, and feign is really one of your more frequently used abilities
