As i allready mentioned in the previous page on the starter-build, the main difference is that you will have gathered some end game gear and starting to lack the hit needed. For this reason you will have to adjust your build to the one above. For more info about why some talents are picked i recommend checking out the hunter abilities page. 

​

Note: I do see some hunter's picking up talents like efficiency and rapid recuperation for mana.. the hunter does NOT need those, when buffed you will highly unlikely run out of mana and if you do you can allways use a potion or the viper aspect to regain mana. wasting talent points is NOT the way to solve your mana issues.
