In my first draft, I started this article off with a detailed explanation of what my main problems with Single-Minded Fury are. I still want to talk about those. But first, I want to say this about the talent.
It's crazy-fun. I've been raiding, Raid Findering and 5-manning with it all week, and frankly I love how smooth the rage generation is. If you ever played fury back in The Burning Crusade or even vanilla, before TG was a gleam in a designer's eye, SMF will be familiar and yet different to you. What's changed? Well, you don't use Whirlwind as your second attack anymore; it's purely a trash ability now. Raging Blow and Bloodsurge instant-cast Slams give you more to do but take the concept of rotation and shake it up, meaning that you're watching for procs more than ever. Colossus Smash gives you a very-long-cooldown ability that you're always going to prioritize. But for all those changes, the talent is still you dual-wielding smaller, faster weapons.
If you were the fury warrior with the Vanir's Fists in late BC, you'll recognize what this talent does for fury. If you leveled a fury warrior in Cata, it's exactly how levels 1 through 68 went. It's a fairly simple concept to grasp. You're not the warrior crushing everything in his path with raw power, and you're not the one using discipline and weapon control to make precise strikes, either. No, you're the one with speed and relentless assault over finesse.
