I rated you back up earlier because you're wrong but smart enough to discuss stuff with so no point rating down.
That said, your first post is spreading bad information and I can understand ratedowns for that.
I'll compare the video's spec with the Cookie Cutter spec
The first thing where he goes wrong is Point of No Escape: Bosses are not affected by frost or freezing trap so those talent points only work on adds.
Lowering the chance to resist on your traps is more effective for adds (as, as far as I know, traps still use spell hit) and the shorter cooldown on disengage is good because it's the single best ability we have for raids, nothing like moving twice as fast and efficient because you're disengaging to where you need to be.
Next he talks about how he would want 2 points in serpent spread for "real dps", I'd say just read what it does and think about it for 10 seconds and you'll figure out why 2 points in there makes no sense. All the second point adds is one more tick of serpent sting, the damage you get in AoE situations from serpent sting is very little, almost all of it is multishot itself and improved serpent sting. And if that isn't enough you'll either shoot a new multishot within 6 seconds or the mobs are dead.
The next thing he does is going into BM, he picks up 3 points in One With Nature for 30% more attack power from AotH, 30% sounds like a lot but in reality it's only (638*0.3=) 191.4 AP, assuming that 1 AP = 0.7 dps this means that you're getting (191.4*0.7=) 133.98 or 134 dps from 3 talent points or 44.66 dps per point, that's very little when you're doing 14-15k dps.
Then he spends 2 points on an ability he admits he will never use while right next to that is Bestial Discipline which increases the amount of special attacks your pet can do and thus increases your pet's dps. To be honest these two points should have been a really big DO NOT LISTEN TO ME sign.
After that he spends points in Frenzy and Frenzy is good, however he has completely overlooked the 4 points you can spend to increase the number of special attacks your pet does in Marksman.
He does talk about Careful Aim after that, but he is making no sense, wanting it tested (It's just math... and simple math at that) and somehow thinking that you'd completely ignore all other shots when above 80% of mob hp.
Below is the math for Careful Aim:
5 minute fight, 1 minute spent at 80% health or higher.
Cobra shot hits for 5k, crits for 10k.
Hunter has enough haste to get 1.66 second cast time of cobra shot.
In 1 minute, you shoot 14 explosive shots (4 from Lock and Load), 3 black arrows (this assumes that you are using the PvP gloves as you should), 1 serpent sting, 1 hunter's mark which takes 19 seconds.
41 seconds of cobra shots left you wll fire 41 / 1.66 = 24.69... cobra shots.
Out of those 247 cobra shots an additional 60% will crit which means 24 * 0.6 = 14.4 extra crits, each crit adds 5k damage for a total of 14.4 * 5 = 72k additional damage.
72k over 5 minutes is 72000 / 300 = 240 dps or in other words 1 point in Careful Aim gives 75.3 more dps than 1 point in One With Nature and that's assuming you're wearing blues and are not raidbuffed.
