No - the entire rotation is built around setup and never feels like you've made a payoff, especially when the core of applying and bursting wounds feels so weak.
UH has way too many cooldowns, on top of being a class that has a pet AND dots makes your "normal" abilities of SS / FS / DC feel incredibly underwhelming. This is on top of low mobility and little to no visual identity compared to frost (or any other melee for that matter).
The spec suffers from nearly every possible issue a spec can have - poor mobility, rampup, pet AI, bad target switching, GCD exacerbation. And for what? Quadratic scaling AoE? Does not seem like a good trade off to me, especially when many classes bring strong AoE without suffering from the other issues.
