Agreed with OP. While goblin background is pretty, it doesnt fit them at all.
Sadly I think that because goblins are one of the least popular races I dont think it will change. Our only chance seems to be their model updates - which is going to be their tiny spotlight. If they wont get it now, they wont get it ever.
While we are at the topic of neglected goblins, I would also like to raise the point that they cant be monks for fucking no reason, which infuriates me as well.
