how much party damage do BRDs and MCHs actually give?

[KaiSunstrider]

Let's for an instant assume crit works like dhit. It doesn't, but for the sake of simplicity let's say it does and state that it didn't scale in damage the higher it went per individual players crit stat. we have x(1+0.45*(2/100)). with x=damage done this comes out to x(1.009). In other words, a 0.9% damage increase.
There is no way in the world that a 2% bonus to crit could give a 3% bonus to raid damage. The real heavy hitters of a BRD's rDPS utility comes from Battle Voice (which actually IS an over 3% increase for it's duration but only for it's duration) and Foe's.

Isnt the base chance 35% + chance from rating bonus damage. So x(1+0.35*(2/100)) which brings that down to 0.7% damage increase unless we consider that everyone has at least 5% crit naked and then it moves up slightly.
