The Goblins you speak of shall be more powerful! It says that the monsters were frozen in time. In the Goblin races book from Death To Dorgeshuun, it says that the goblins from the third age were more powerful and organized. Another page says that "sketchy record that have survived from the third age..." That is proof that there were goblins then, and if JaGex say that there are goblins involved, then there will be 3rd Age Goblins in the God Wars dungeon! It also say that goblins were used as footsoldiers to fight other Gods, and that their armour was also more powerful. (3rd Age Goblin mail: cross your fingers.)
