Why You Shouldn't Use Fracture

[SofiyaGlaston]

First to address the BB>BB>SE combo.
In order to maintain the buffs from the SE combo at 100% uptime, you'd actually have to do BB>SE>BB>SE (As Storm's Eye only has a 15 second time, with GCD being ~2.5 seconds). But moving on.

Factoring in Maim and SE buffs (discluding Berserk because its buff contributes to a portion of damage equations) Each set has potencies/gcd as followed:

Fracture: 134/240** (total 374/gcd)

BB combo 277.2/gcd

HS 198
SS 264
BB 369.6

SE combo 268.4/gcd

HS 198
Mm 250.8
SE 356.4

Using just the basic Potency per GCD and not worrying about TP usage (as unless the fight is incredibly long, there's not much to worry about) Fracture is a large amount of damage and should be used regularly..
Basically: BB>SE>Fr>BB>SE>BB>SE>Fr

**Fracture's dot does not gain benefit from the SE buff as it is not considered "Slashing"
