I'm guessing it would be as the author suggests, something whereby we can take advantage of space elements. I do like squeezing to a side crevasse or, given that I'm short, just walking through the grass in Nagrand is enough to hide me. I think there will be a cool down of moderate duration. Perhaps it's a talent that would "proc" only in certain situations. Honestly, I can't see that it's a challenge to your racial. We take a "wait and see" approach to all of this. I would be thrilled if all they did was fix growl. Still waiting on those 100 count bags however.
How do you make sense of all the beta hunter changes? I think how Camouflage is implemented will make a difference. I am a dwarf but I immediately thought of my nelf friends and their cats who get into a position and fade. "Damn, that's cool," thinks I. "Wish I could do that and pop out at the enemy."
Do hunters need a true taunting shot? Blizzard says, "Yes!"
Another nice change coming soon to a beta build near you: Distracting Shot will work more like a warrior's Mocking Blow, forcing an NPC enemy to attack you for 6 seconds. This is the answer to my prayers I've sent up while trying to trap while grouped with my paladin tanking friend. Once enemies start attacking her, it seems like there's no way to peel them off again, and this sometimes made trapping my designated target difficult to impossible.
This obviously makes our traps much more powerful, and reinforces our class' mastery of PvE threat-management. Abilities like this, along with Misdirection, and Feign Death mean that hunters are the go-to class when you want your enemy to be in exactly the right place at exactly the right time, especially when someone else is having trouble and things start to go wrong.
It should also let us respond much more dynamically to situations that would otherwise be out of control. Suppose your healer draws threat (as they may be more likely to do without spell downranking) and your tank can't get there in time. You will be able to taunt that hazard over to your new-and-improved Freezing Trap just as fast as your own brain's reaction time can manage, which should give your tank enough time to see what's going on and reacquire that target's attention at his own pace.
