Eh.
https://www.warcraftlogs.com/statist...91&dataset=100 quite clearly shows BM hunters are top on gruul at every. single. percentile. Not just "super lucky 90-99th percentile". EVERY. GODDAMN. PERCENTILE. The only thing that they're not is "max", because one lucky arcane mage with gear out his ass beat hunters (max just shows the highest log from each spec).
Are you going to argue that the 25th percentilers just got "super lucky" xd? Or could it be because, as a spec, BM is doing better than every other spec (and thus their 25th percentiles are still going to beat other classes 25th percentiles)? Naw, couldn't be. Let's just blame it on RNG.
Disclaimer: I hate the RNG bullshit that is BW resets and Frenzy procs as much as the next guy, but just because it's annoying doesn't make the class any less powerfull. Even with moderate RNG, at all levels of play, BM has impeccable performance on singletarget VS any other spec. Hunters. Are. Strong.
