Since we are back in our timeline to deal with the Burning Legion on the Broken Isles, and Gallywix is not really doing anything else as always. Maybe the Venture Company has taken what remains of Kezan that hasn't actually sunk but greatly damaged from the eruption of the volcano, lore speaks of a titan-made chalice hidden in the depths of the Undermines that had power enough to rejuvenate the Sunwell, but since it already got rejuvenated it could be used for something else that the Venture Company could end up misusing and this could be just a selling point for Gallywix to use to convince the other faction leaders of both horde and alliance for his own selfish desire of trying to take the Undermines for himself the Bilgewater Cartel. Would be an interesting patch having an event to revisit and actually explore the rest of Kezan since we only saw like 1/5 of the island as new starter goblins. Or would this be more fitting of a south sea or great sea expansion later on instead of a legion sub patch like they had Isle of Giants as a patch island content?
Could lead into Trade Prince lore and meeting the other cartels with a war between cartels over the island that doesn't want to share it. Gallywix gotta get some kind of action other than the minor action of him during the invasions in Azshara.
Could also lead to new mechanical pets for hunters to wander the island like a Rocket Chicken

? Or any other mechanical pet to be added in since duh we dealing with Goblins now
