How Long Does It Take to Design a Boss?

World tiers generally progress as you go up in levels. We don't want to over reward world tier two and have players who feel like, Oh, well, I would be stupid. If they're not actually ready for that challenge. It takes maybe two or three times as long for us to design a boss than most other features. But the thing is that you've got bosses that are, you know, at the end of a dungeon, for example. And so that tends that that translates into extra time.
