As prot you get avenger's shield, but since you have concussive shot on you, that gets you pretty much nowhere. HoJ, you say? Can't get in range, and if I do, I spend most of my 6 seconds of stun slowly crawling up to the hunter, and then I either get trapped/scattershotted/disengaged. Then this dumb cycle starts again.
As ret, you get a mini-sprint from judging, but again, concussive shot negates that completely.
I am seriously at a loss on how to defeat a hunter.
