I guess it would make sense that this burst dps is directly tied to our weapon ratio, by giving greater returns to high end raiding. (it has been said a couple times now that in mid-tier lower dps guilds our dps is still able to compete...atleast up to a point)
Just boosting Empathic Fury/ Bestial Alignment would do this...be it by adding more to crits/modifiers, or even adding flurry chances to it, the impact from these disc/AA would benefit you more, the higher ratio weapons you have equipped. Imo, as it should be.
The problem is bsts dps hasn't been as weapon dependant as other melee/hybrids are, so we get much less returns from weapon upgrades too, in comparison to other classes :/
Because of this handicap with weapons, our discs need to be much more powerful than melees discs are, because we attack less times than them, and gain much less returns from a burn disc.
