Question about Fracture

[Ragology]

Taken from this reddit post, Fracture is a Gain for WARs.

Average potency of Eye+BB every combo with just slashing is:
(150+190+270+150+200+280) * 1.1 / 6= 227.33
Throw in a Cleave every 8.5th GCD and you get
(227.33 * 7.5 + 550) / 8.5 = 265.29
The potency you gain per GCD dedicated to building and using Cleaves, presuming you end every encounter with a Fell Cleave that results in 0% overkill:
265.29 - 227.33 = 37.96 potency gained over raw Eye/BB per GCD that is either an Eye/BB combo or a Cleave
Potency gained per Fracture over Eye/BB is 310 - 227.33 = 82.67 per GCD dedicated to it.
Every 8.5 Fractures you use pushes five stacks out of your rotation, so it nets you the gain from using Fracture minus the loss from building and spending stacks on each relevant GCD: (82.67 - 37.96) * 8.5 = 380.04 more potency gained by using Fractures.
Note: these calculations don't include Crit, which is a notable omission because the average non-Cleave ability will gain just over 3% potency from average stack distribution if you gear for Crit, whereas each Cleave will gain about 6% due to always benefitting from five stacks. This minutely shrinks the Fracture potency gain, but doesn't even come close to affecting the conclusion that Fracture is a DPS gain.

Despite all the math, I generally avoid fracture in short fights. I'd say if a fight is 3 mins or less, you should really only be applying it under the effect of some kind of buff (berserk / unchained). Other than that, it doesn't boost your dps by a whole lot. Longer fights where there are no stops, and you have full uptime for a prolonged period of time, fracture will start to give gains overall.

Something else to keep in mind, is if a boss or monster becomes un-targetable, it is immune to all dmg, and that goes for dots as well, so don't waste a GCD on fracture if something is going to jump, it won't do you any good.
