You can root and kite I guess, but this does not assure one’s victory. What if the Demon Hunter chooses to disengage you in battle until you decide to stop kiting them?
Spamming disable root, RoP, double port. Anything to shut down there damage. Other wise you can try being aggressive on opener so they end up using everything to live putting them in a vulnerable spot and youll still have walls and karma. If they are low hp and try to fight you can agressively karma too to finish them out. They only have good healing if they can damage you so if you I kite well enough and fist parry they cant heal.
