Quick disclaimer: the formatting on this is going to be difficult, so assume that integrals are taken as limits from 0 to T, where T is total fight duration.
The "expected value" of your total damage output is given by
C∫ p(t)w(t) dt
where C is the crit multiplier, p is the crit rate at a given time t, and w is your damage output as a function of time. If you're playing a job with a fixed crit rate, this simplifies to
Cp∫ w(t) dt
Xeno's argument implies that w(t) influences this value. My point is that it doesn't, so long as the area under the curve is the same. It doesn't matter if you rearrange WAR's rotation from one with heavy burst to one that has more consistent dps as long as the total damage is a constant.
Now you might say: WAR's p(t) does vary with time, because it is linked to their resource gauge. Which is correct, and is also why this is an underestimate. WAR actually is more likely to crit on higher weighted portions of their rotation than this estimate would predict. Which is why they're actually privileged, not penalised.
I know that this might seem counter-intuitive, but probability theory often is. That's why people get obsessed with perceptual errors like "winning streaks" in spite of the fact that we've proven them to be, time and time again, mathematically false. If you fail to crit on your Berserk, you'll do less damage. I get that. But it all comes out in the wash when you look at averages.
