The strafe course for the dh is currently using the Zigzag path for the WW barbarian.
So basically the only way is to kite when you get too close to the elites/boss.
Drawback will be then that your dh keeps strafing close, and running away (even worse vaulting away !! if you're using vault).
You'll get there, you will kill the elite and not die, but it won't be nearly as satisfying as if you were doing it yourself, strafing cleverly around.
ps: if your dh is not kiting at all, then it might be due to the dh initialization bug I'm talking about in another thread.
I'm currently trying to find another function for the strafe path. I've tried to use MainFindSafeZone but wow I'm too far away. So still working on it...
