Hunter TalentsFollow

Can anyone tell me how effective Arcane Shot, and the various Stings are? I wanna do a Marksmanship build Hunter, however, I would like to get Wing Clip boosted with Talent, and Aspect of the Hawk buffed up with talents as well. This kind of puts a strain on the Marksmanship tree, and I was just curious what talents right now in the Marksmanship tree are possibly worth skipping. Thanks for any help.
