Hunters were never built to be a great solo PvMP class. I have been playing the moors on and off since SoA days. I remember two very short period of times where the hunter had some great advantages. The proper response was to nerf them of course. I think nerfing the class when it was needed sparked some trend. They then became nerfed every time a creep yelped loud enough after being killed. Many of the changes did not bring balance to the force. I recall when Desperate flight in combat was removed for MvMP. Because you know, hunters were abusing it. A creep could not get a KB on a hunter, once every 30 minutes. It is not like wargs can do that every three minutes. Having that stupid yellow mark when you go for a heart seeker? That makes perfect sense because a warg needs a warning when they need to start their run away or hide skills. Then there was that great nerf to remind hunters how useless we really are as soloers, the "bug" of not being able to track stealth mobs.
I am being somewhat sarcastic. I still love to solo even though I know I will lose most of the battles. But in groups we do shine and I think this is the point of the devs. Giving us DF back, adding some better self heals, or giving us cry of the predator back will just make us think we are better then what we really are. So accept your role as a powerful group DPSer, or an OK group CC, or a "run around like a chicken with their head cut off" harasser (which is currently my favorite moors build) and watch your rank rise!
