The short answer is: You don't; at the moment there is no making sense of all the Wrath hunter changes. We find ourselves at the mid-point of Blizzard's mysterious scheme for hunters, right in-between significant changes already in-progress and vague changes which they've promised or the future. We remain uncertain about which ones are going to make it live, which will be changed again, and which will be removed or added later on. Any analysis we do right now (and indeed much of the analysis we've already done) may or may not be completely out of date in a matter of days or weeks, and if your head hurts from all the ups and downs of turbulent beta-zone theorycrafting, rest assured that Scattered Shots feels your pain.
The long answer is: Even though the jigsaw puzzle isn't complete, it's still a pretty neat picture to look at. Today isn't the day for point-for-point talent analyses plus spreadsheets of sting/shot-damage coefficients -- what a headache that would be. No, today is an opportunity to stand back and look at how all this is beginning to fit together, to see how the path our class is trekking through the wilderness of beta-testing ambiguity solves some of our long-standing problems, gives us more of what makes hunters great, and leaves us with several crucial questions mysteriously unanswered.
What follows, ladies and gentauren, are the X-files of hunter beta mysteries, a fuzzy look through the crystal ball into the future of our class, the thrilling buildup to the surprising twist that comes just before the epic climax of the Hunter Saga season finale and leaves you hanging on the edge of your seat, biting on the tip of your fingernails, and gasping for air in the thrall of cliffhanger suspense.
