As far as a video goes, I haven’t seen any myself of the new stuff for hunter. The current videos are pretty relevant though. Just that some of the skills now do damage.
-
Coursing = Good against all but bosses
Rush Dog = Good damage since its rework, though you have to actually press the skill for it to go off. (We will miss you auto Rush Dog, you were to good for us and we didn’t notice 
)
Snatching = Exceptional against flying enemies, including most bosses.
Your build isn’t bad. If your dead set on the companion thing.
Suggestions:
- You would want at least 3 or more points in Snatching
- Growl is fine at 1 point or 3 points
- You don’t need 10/10 Circling. As far as we know so far not many monsters have higher than 5 or 6 AoE Defense (This is my own knowledge) so 5 points in Circling is good enough.
- Hanging Shot in all honesty should be 1 point. As a hunter and Falconer you have so many CC skills that getting damaged is not much of a worry.
- Put some points in Hovering, it’s like the auto attack for your falcon.
This is my knowledge and 2 cents. Take what you will.
Edit: Oh yeah Oblique Shot that high may give you mana problems, so be careful when leveling it. That or put points somewhere else (I.e. level 1)
