Talent Build Comparison?Follow

First suggestion, use the wowhead talent calculator (on wowhead.com). It's easier and it loads faster. Second...

Your build is not a bad solo build. It allows your pet to be a much better tank by being able to take more hits (catlike reflexes, endurance training, thick hide), allows you to hit from farther away, and allows you and your pet to contribute tremendous damage.
The build that is mentioned has the most possible damage-dealing potential (IAotH, dropping to 4/5 frenzy to pick up animal handler, gaining a lot of crits, etc). So while your build is fine for solo, and still wouldn't be too bad in a group, it is not the supreme DPS that a 41/20 build would have. (The only real difference between the 2 popular 41/20 builds is substituting imp mark for efficiency).

Now, also know that the talent section here doesn't include the best builds, but the most popular ones. There is a survival tree that at least one hunter per raid (meaning 25-man) should have, but it isn't even listed. And the purposes of the builds are not mentioned, where there are different purposes for some builds (i.e. focusing on instant shots and burst damage for PvP, survivability for solo play, CC or off-tank ability for 5-mans, or pure long-term DPS for raids).

So, while you are levelling, it's considered better to pick up the talents that will help your pet survive longer, because it's your tank, but when you hit 70 and start raiding you may want to respec to more DPS.

1. The reason the other build is great for raiding is because it focuses on your damage-dealing potential. The first build gives your pet more survivability, which is very helpful for leveling or even for soloing at 70. The thing is, in raids your pet would probably be 1-shotted, so you're not likely to off-tank at all with it. So, only when you start doing raids or heroics regularly, which is at level 70, would I recommend a pure DPS build.
2. IAotH is the only first-tier BM talent that increases DPS, and therefore should be in every BM DPS build. However, if you go marksman or survival, it is still an easy 5 points to spend that will up your DPS. You will probably see a 4% increase in your damage-dealing potential by having hawk, so yes it is great. But, again, in solo play you would better off with a stronger pet than a stronger bow if you go down the BM line.
3. Actually, while some survival builds are based on traps (and are common for heroics), once you hit raids the survival spec is this. It focuses on agility and crit, and every time you crit you get mana back and temporarily give all melee DPS and fellow hunters a huge increase in damage potential. This is a high-DPS build (albeit not as much as the BM spec, but you add more to the raid).
A trap-based SV spec wouldn't really use stuns, but would have a lot of crowd control, and would probably look something like this. With this build, you may sacrifice 4-5% of your damage dealing potential to include longer traps with a shorter cooldown, scatter shot, deterrence, and wyvern sting.
4. Hawk eye will not really hurt soloing or grouping. In fact, in some ways it helps. It DOES increase your range to 41 yards, which means you can pull from farther. However, if you fight from closer to benefit from auras or totems, you may see some difficulties. Also, it is 3 talent points for no real difference if you're sitting there shooting at 20-30 yards, whereas if you were to put those 3 points into finishing mortal shots you could see a 3.6% increase in your damage from those 3 points if you have a 20% crit chance (which you should have for raiding, if you're BM).

Caldone, there are 2 problems with your build.
1. It's marksman.
2. It's marksman.
I know that's the same problem, but it's just so important I felt I had to say it twice.

Oh, wow, you used my same arguement against me. How can someone with that much wit possibly make an infallible build? /sarcasm off.

I fully agree with Caldone, MM is awesome for pvp only, not for pve.

Thats because if entrapment procs, you wont notice it.

And just spec 41/20/0 or 5/20/36 for PvE ;) (0/20/41 also works)
Just face it, MM isnt a good pve spec anymore beyond moroes.
