Please do add more rumble. I really liked the rumble in Diablo 3 (PS) and Diablo 2 (PC) It’s so satisfying.
I find the beta’s implementation to be very lackluster. All attacks need to have a tactile sensation. If people don’t want vibration, they’ll turn it off.
At the very least, add an option for full rumble. It may sound dumb, but it’s part of what makes the game so addicting for me.
