It's nice to toss in at the end of a Berserk and/or Unchained for the extra damage. The way the timer on Berserk/Unchained go, you won't get more than three full combos, and usually you'll have an extra GCD to spare. Tossing Fracture in there is nice, particularly if Maim is up as well. It's good damage, just not something you need to keep up all the time when tanking.
The thing about me is that apparently it's very hard to tell when I'm drunk. So I feel like I'm walking sideways on a UFO and everyone else sees me doing the robot like a pro.
i have bathed in the blood of many. my life was spent well.
