The goal of Diablo Stats is to track hero progression over time and make item comparisons easier with built-in damage and effective hit point (EHP) calculators. It's a great way to see how your heroes' stats change and progress over time, and Rek would really enjoy if other players jumped in and offered feedback so that he can further refine his project.
You can get started by visiting Diablo Stats and typing in your BattleTag into the "Add or Search" box on the top right. From there, it should generate a page for your account for you to dive into and compare with other players.
So make sure to check out Rek's great new site, and take a few moments to leave feedback so that he can take it to the next level. You can do this by leaving a comment in his original thread over on Reddit, the thread he created on our forums, or you can drop a comment below!
