Looking for a Few Good Orks

[unless]

Also checked on the engineering, it is complemtary to the mining skill and at first can be used to make small area effect explosives.  I did not actually try any of these out to see how they actually functioned.

Engineering seems like a sort of catch-all tradeskill for making "neat" stuff. In addition to the explosives, you can make a pet mechanical squirrel, charges to blast open locked chests, land mines, speed-enhancing rocket boots, and (my favorite) jumper cables that you can use to try and resurrect someone. This is all explained on the official WoW site, here.

I'm not in the beta and so I don't know how useful all this would be, but it certainly seems pretty cool - probably the skill I'll try out first.
