General Manager of Diablo Rod Fergusson confirmed we’re going to hear more about World Boss Timers in the upcoming Developer Update Livestream on October 4. Chances are the timers will be implemented in the Season 2 patch!
It appears players will no longer need to rely on third-party tools to figure out world boss timers. Rod Fergusson replied on Twitter to a question about world boss timers that “you’re going to like the streams”, suggesting we may see timers implemented in the forthcoming update.
