Now that's not to say I never use it. I still do which is why I have it on. In the end, I found the best rotation is to not use it in your "first phase" of your rotation, use it on the 2nd, don't use it on the third. The entire rotation resets at this point and repeat (don't use it on the first, use it on second, etc).

Also I do use it in situations/bosses where I know I will not be able to hit the boss constantly. He may move around, or I may need to leave the boss to hit adds. At that point, I'll hit the boss with all the DoTs, including Fracture, just so damage is still ticking on him while I'm not connecting with him.

So as you can see, it's still useful in certain situations and I do still keep it on my cross skills. But I don't think it's to be used every single time. Again, the theory crafting pie in the sky thinking may say one thing, me spending hours hitting training dummies with a parser tell me another. Real world > theory.
