I was looking through engineering today, and a lot of it doesn't seem particularly useful for beastmaster hunters =/ Bombs and grenades cause stun and large damage, which will tend to pull mobs off your pet, and the bombs/grenades tend to be the big draw to engineering apparently. That and jumper cables, but...who cares if you wipe? You have to take some time to walk to your body, it's not THAT big a deal ^^; there's no real penalty to dying in WoW, lol.
Maybe it's just me *shrugs* if you can prove me wrong, please do >.> some of the engineer stuff is nice, but it mostly seems like a "toy" profession for beastmasters rather than a useful one. I may just wait for jewelcrafting :P I wanna make jewelry/gems ^_^
