Well, I read the basic premis. I never bother reading skill descriptions for classes that are made-up, as it's a waste of time. They won't get implemented but at least your theme and idea is pretty strong.
Would love to play a Goblin Monster Hunter - "Hey, i'm outta ammo...Ooo, look at all this scrap? Surely I can build/throw/explode/ignite something nasty out of all this junk!" Not sure what races would be excluded though. Possibly Pandas, Night Elves, Worgen, Trolls and Taurens. I could definately see Draenei, Gnomes and Goblins as this class, as well as Undead. Orcs are a bit of a podge, but they do build war machines. Same goes for Blood Elves with their golems.
