Why there are no goblins in LoS2

It's a little known fact that lords of shadow's "goblin trials" are best approached in areas where goblins infinitely respawn due to being necessary for certain barriers.
so naturally I got the impression that my kill count of 734 goblins in the course of 30 minutes might be implying that gabriel belmont single handedly caused the extinction of goblinkind long before he became dracula.
