This is the most common used MM build when you are starting to enter ICC raids but still get a lot of your hit rating from gear, this is actually THE major reason it is different from the more advanced build. No need to put points into foccused aim as you have the hit covered! Instead put them in improved hunter's mark. 

​

Note: I am a fan of the hawk eye talent adding 6y to our range, you can also pick that up and i recommend it! the reason i did not put it in the build is because you might end up getting used to the range and having to put them back into focussed aim later on can cause more issues for some hunters.
