I’m one of the ones who’s annoyed about fighting Gallywix, because I’m just tired of fighting Horde leaders and former leaders.
The devs were clearly determined to oust him as Goblin leader, so, fine, whatever. But if they want to bring him back, there are ways to do it that wouldn’t involve him returning as Goblin leader or as a loot pinata.
As an example off the top of my head, he could be trying to rebuild his fortunes by sailing around in a merchant ship. It would be neutral territory, where players of both factions could buy silly “money sink” cosmetic items. Maybe Griftah would be on board as well. The captain’s cabin would have a laughable, cobbled-together “throne” and a desk full of amusing readable items—drafts of letters where Gallywix tries to ingratiate himself with the other cartels to get a loan. If you descend all the way to the hold, you find a black market auction house. This ship could reappear in future expansions in different locations, possibly getting a little nicer (or not) each time.
