For classes who rely on energy regeneration such as Rogues, things have also changed significantly since the classic era. Regeneration used to occur in chunks based on the server “heartbeat.” So, to gain 20 energy, it would take a full two seconds. Today, the system is smoothed out so that that 1 energy regenerates every tenth of a second. This difference changed the timing of being able to use certain abilities. What seems like a minor convenience today actually changes the very flow of combat rotations and burst capabilities in classic gameplay. We felt this was important to restore to provide this authentic experience.
The first—and among the most important—decision we had to make was which version of the game to focus on. As many of you have noted, the classic period was two years long and full of changes. Core features like Battlegrounds were introduced in patches after WoW’s original launch, and class design similarly changed over time. After careful consideration, we decided on Patch 1.12: Drums of War as our foundation, because it represents the most complete version of the classic experience.
