Primary note of importance:
Before you look at the guide, please please please do not simply copy over all the skills I use. Also, below is NOT the build set-up I use. It is the core of the build. When 1.6 dropped, I had this build idea. I PvP'd with this set-up for about a week, and throughout that time, I changed many things. Some were easy decisions and some very difficult. These decision improved my game-play by complimenting my personal play-style and philosophies. Nevertheless, below is the core build, and it should be treated as the most "basic" set-up. I will give my preferred set-up later in the post, but I do not suggest that you simply copy what I use. Instead, play around with the core build and swap the skills around to fit your own needs and play-style. I will give several good skill swap choices and explain their pros and cons to help out the less experienced players. Keep in mind, not only can the core build's skills can be swapped, so can the gear set-up. I will also include alternative armor sets to use with this build along with explanations as to why to choose them to help you guys with the decisions.
Also please keep in mind this post is not entirely finished. I will be adding more on in the next few days and even more whenever I gain new information or ideas. In the meantime, I will answer any questions the reader may have to the best of my ability as soon as I see them.
Edit: Please take some time to read the comment section as well. There are some good questions down there and it may be beneficial to the reader to look over the questions and answers to gain a better aspect of the build. There's most likely some general information as well; all-in-all, doesn't hurt to look!

Skill Set-up:
The below skill set-up is not my preferred set-up! This is the finalized draft of my theorycrafting. My preferred build can be seen in the spoilers following this one. Please keep note I'm posting my theorycrafted version to primarily show how much a build can change based on personal preference and extensive testing. However, this is not to say the theorycrafted version cannot be effective.

Skills Swap Suggestions:
Truthfully, you can make any skill swaps you'd like. The follow are just my personal suggestions. This does not make them the best choices for you individually. Try out different skills and see how they fair for you.

How to utilize Magnum Shot:
But Aetcharian, why not Sword & Shield instead of Bow?
What about Dual Wielding?
