At the moment, not really. Rage synergizes well with Jing Wei, but it's just far too weak currently for me to ever justify using it. If anyone could make good use of it, though, it would be Jing Wei. The good thing about Rage is that it has over double the critical strike chance of most critical strike items. This allows you to build less critical strike items while still dealing consistent critical damage. However, it offers no other benefits beyond a tiny amount of power, while items like Atalanta's Bow, Wind Demon, and Shadowsteel Shuriken do. I find that you're often better off just getting two of these items over getting Rage. Feel free to experiment, though!
