First impressions - it' rather buggy, and there's lots of people around since a new wave of invites was sent out. Hunters work great with focus - in PVE. Marksmanship and survival hunters can't do anything in pvp at the moment, everything rapes you. What was cool about mana was I could use the abilities I wanted. I'm brilliant at hunter micro managing, and there's nothing better than pulling a 3v1 and then popping a potion and proceeding to kill a fourth person. I would scatter someone while focus silencing another person, all this while nuking the hell out of another opponent. Then, I would launch a freezing trap in mid-air while escaping with the deterrence + master's call combo. Now, I'm not able to do any of that. Hyjal is a warzone and everyone, especially MAGES, can you believe it MAGES are running me over because I can't use a single goddamn spell.
Steady Shot is the only way to regen any focus, and you have zero chance to ever use that in PVP. Currently I'm able to fire an Arcane Shot and use my pet stun. After that, I'm out of focus for 4+ seconds, during which I'm useless and already killed. Not cool, but at least it's early in the beta, things can't stay this way. Beast Mastery seems the most fun at the moment, and the tree is home to a number of brilliant PVP talents. It's quite difficult to measure my DPS, so I'm not sure how it compares to other classes. Also tried an instance, but our tank sucked and everyone left.I got so tilted from losing in every PVP encounter that I logged off early.
Gonna play more later, pictures and less whining to come.Mages... *facepalms and walks away*
Fox, in turn, for the reasons explained before is bloody useless. 22% is very little and pales in comparison to steady spamming with Hawk. 
But like I said they've said they'll be playing with costs for some time, nothing is set in stone.
