Notes:
As you can see the "Dark Ranger" Talent is in the last place in the last row. It's there on purpose so those who don't want that class fantasy (and the benefits the talent grants) can easily dodge and still be able to choose the "Legacy of the Windrunner" and "Wailing Arrow" talents.
Note that the "Dark Ranger" talent only changes Nature damage to shadow damage (similar to the rogue subtlet's new talent: "Dark Brew").
Also, the speed boost benefit is 14% to perfectly synergize with the Hunter's "Agile Movement" talent which once full grants us 6% speed. Adding "Dark Ranger" with "Agile Movement" we have a perfect 20% speed (like rogues and other classes).
It is worth mentioning that the "Dark Ranger" talent does not make the Hunter MM overpowered by granting 2 additional talents, after all, these two talents replace other 2 similar talents from the Hunter Baseline.
So... the "Dark Ranger" talent is fair and fulfills the role of giving Hunters the full Dark Ranger class fantasy without undermining the choices of other Hunters.
p.s: To make it easier to deploy the talent without having to juggle the points allotted for this area of the talent tree, the "Wainling Arrow" talent has been transformed into a 3-rank talent.
Personal Note: Check this out... I'm not asking for an entire class of Dark Rangers and not an entire spec just for Dark Rangers. Well, the devs just need to change 1 single talent in the MM tree and (added to the recent DR skins they gave us) the Dark Rangers enthusiastic Hunter would finally have everything to play with this class fantasy.
