BM hunters are not just dead last. There's outlaw rogues which are in a bad spot as well but at least there are other specs close in performance to them. Then there's just a massive drop-off in performance and you have BM hunters. And it's not just in PvE.

S6: 5 BM hunter total above 2.2k in 3v3; 1 BM hunter above 2.2k in 2v2.
BM hunters don't have any redeeming qualities. They are just BAD and this is unacceptable in an expansion that encourages you to stick to your spec. Instead of alleviating the issue, Blizzard keeps pushing bad class design on hunters and nerfing them. Yes, BM is brain-dead easy to play right now, but whose fault is that? Instead of buffing talents that promote engaging gameplay (chimera shot, dire frenzy stack management, cobra shot / kill command weaving), Blizzard doubled-down on making the brain-dead choices the best ones.
Things that need to be done:
1. KILL the brain-dead "beast cannon" build
2. Buff chimera shot's and dire frenzy's damage output
3. Revert template nerfs in PvP
4. Improve scaling for surge of the stormgod
