In other words, it's a CC-focused hunter. Bearing that in mind, it's no surprise that the majority of the build's points (43) go into Survival. Fortunately, that tree got heavily buffed recently (in 2.1, I believe), so that doesn't gimp your damage as much as it used to. But let's look at the choices outside Surv first. There's not much to look at: 5/5 Imp. Aspect of the Hawk (IAotH) in Beast Mastery, and then in Marksmanship, Imp. Concussive Shot, Lethal Shots, Go for the Throat (GftT), and Aimed Shot.
Just looking at the layout of the points in those two trees, one thing instantly occurs to me: can we spend those points in IAotH better? It's a strong talent, but it has its downsides. I've heard Aspect of the Viper is more commonly used in instances and grinding, simply to keep from running out of mana. How much does IAotH add to your damage? Well, that depends on the speed of your weapon.
The average speed of a level 70 ranged weapon
is 2.72. According to my calculations, that means that for the average hunter, IAotH should be up about 55% of the time (ignoring the fact that when it procs, it becomes somewhat more likely to proc again). When it procs, it increases ranged attack speed by 15%. So in the long run, having the talent increases your ranged attack speed on average 15% * 55% = 8.25%, or somewhat under 2% per point. And this is where my knowledge runs out -- I don't know how much of a hunter's damage comes from Autoshot, so I can't tell what effect this would have on overall DPS. If about half a hunter's damage is Autoshot damage, IAotH adds around 0.83% DPS per talent point.
Of course, even if it turns out that the talent isn't quite a powerhouse, there's no great place to put points taken out of it. I had initially looked towards Mortal Shots, since we already have a few talents that increase crit chance or proc off crits, but we would first need to spend two more points in Marksmanship. I don't see any very attractive places to spend those two points. So I think we'd better keep IaoTH after all. (That was a lot of math for nothing...but it was fun.)
As far as the talents we do have in MM go, it's pretty straightforward. I would usually shy away from Imp. CS (at least for a PvE build), but that one in five chance to stun would really help out with the 5-pulls this build aspires to. So...on to Survival, the swiss army knife of Hunter trees (yes, it's a knife and a tree) and the bulk of this build.
There are several talents in Surv that help directly with this build's focus: Entrapment, Clever Traps, Trap Mastery, Resourcefulness, Wyvern Sting, and Readiness. Let's take these as given. What else is up for debate? I would seriously consider dropping Humanoid Slaying and taking Hawk Eye instead. Range talents are consistently underrated, and the majority of mobs are not humanoids. The extra six yards on the initial pull will probably buy you more time than 3% more damage and 3% more crit on some mobs.
On the other hand, if you look down to the second tier, you see Imp. Wing Clip, which makes me think that this build, sensibly enough, has PvP as a side focus. If you're going to specialize in Survival, it'd be kind of a waste not to put a little energy towards PvP. But back on the first hand again, Imp. WC would also be useful for the CC game, in case a mob gets loose a little early or something, so who knows. It's almost certainly more useful than Deflection at any rate.
Moving to the next tier, you can't really argue with more health, although I also can't help but wonder if a couple points from Survivalist might not be well spent in Deterrence and Counterattack. I've never played a Surv hunter, so I don't know first-hand, but I hear Counterattack is a very popular skill.
Survival Instinct and Killer Instinct are both clearly valuable (not to mention KI is required for Wyvern Sting). Lightning Reflexes is a bit iffy on its own, but Expose Weakness, on top of our high crit chance, makes it almost certainly worthwhile. And there aren't any choices left after that; Master Tactician is required for Readiness, which we need.
Overall, I'd have to say for its stated purpose, this build is about as good as it could be. I would switch out Humanoid Slaying and possibly drop a few points from Survivalist, but aside from that, good job, Mr. X. Of course, there's the whole question of whether you approve of X's goal with this build in the first place, but there's not much factual to say about that. I'll just quote one of my all-time favorite WoW Insider comments, from quite a while ago
