goblin faction trap abilities

[denny31x]

I don't know it is possible or not but it will be cool if goblin faction have abilities to set a trap like in the movie, where thorin companions sleep in the cave and suddenly they sleeping in goblin trap then fall into cage
Sorry bad english

I like the idea that the goblins are tinkerers accostumed to dealing with rough mechanical stuff and evil pointy machines. So the ability to set traps in the battlefield would be a great original idea for the faction, whatever the form these traps actually take in the game. But I hardly doubt that it couldl be something "like in the movie".
