Ancient keys are worth a pretty penny, and I don't think winning a $50,000 spawner from a key that costs around 1 million is very fair. I would like to see maybe higher money amounts added, and maybe the chance to receive one perk key from the Ancient Chest. This way, it would give the player another reason to use the ancient key. But ultimately, zombie and skeleton spawners should not be a prize for using an expensive and rare key that costs almost 1 million in-game dollars.
