Demon Hunter

Philosophy
We've chosen to focus the Demon Hunter more on Cold skills and away from Poison skills. This change allows us to provide more Cold options to the Demon Hunter. Going from five to four elements for the class overall increases the likelihood you'll get an elemental damage bonus you want.
Preparation – Punishment has been redesigned. The previous gameplay encouraged using all of your Discipline for offensive purposes, which undermined the role of Discipline as a defensive or tactical resource.
Patch 2.1.0 brings changes to how the heroes of Sanctuary recover Life. Health globes are being de-emphasized while item and skill choices will be more prominent. Numerous healing related skills on the Demon Hunter have been increased.
