For heroics is mostly the same, you can add some Lamordia or MD items if you need but is perfectly playable (though i'll level with xbows and inquis (bow limited aoe options specially on dark hunter and ranged power before epics hurts). For legendary i used this one as a starting point for my main, if you want something ultra optimized to MD/Larmodia gear for r10 raiding this is not your build, if you want to start from 0 to do a bow build this works perfectly after tuning for r1 raids or r10 quest with a lot of room to improve with newer gear.
The only thing that was ultra nerfed from this build is hunt's end + sniper shot combo
Edit: Ying has another guide for legendary, based on this one but still old
