Too add to my experience, seeing 20 boomkins in MoP as hunter, I usually switched target even from a healer to burst the boomy, and usually they would die. Burst is there you just have to know how to use the class first.
" If you want burst, it might be better to stack multistrike and crit as opposed to just crit because the points to percent relationship with crit isn't linear and there's diminishing returns per additional point. The 20% additional multistrike with survivalist also matters in the equation. "
As far as that goes it's true, but past 50% crit by 5 or even 10%? (how?) is really good and the diminishing returns gets a bit of boost around there, but not much further up. The class can really be used as a situational dps at those stats.
