I love the game, but Blizzard a lot of people have been asking you to fix this for several months now. The controller needs vibration for all combat skills. It makes the combat so much more satisfying and punchy. People have the option to disable if they don’t want it. Currently there is virtually no vibrations and the combat feels flat and breaks the immersion 
This HOTFIX broke the vibrations:

Bug Fixes
Fixed an issue where the Sorcerer’s “Ice Shards” ability would cause excessive controller vibration.
