Option for DH to not stand in melee range?

[Inkoosikas]

Hello, is there an option at all for DH to not stand in melee range? I am trying to run Grifts with my M6 DH and it will literally always stand there and try to facetank elite packs which kills it 99% of the time.

So is there an option for it to stay back a bit out of melee range?

If not, is there a possibility of trying to add one?

Thanks!
