3 buttons on my mouse that will never see any use, right click, mouse 3, and mouse 4 because keyboard and mouse is not properly supported.
While I like using my controller, I would love to be able to play this more like Diablo with the mouse. Hoping to see controls expanded and improved in the future.
Totally agree with this, thankfully i have the logitech g600 and i changed it that just for this game middle mouse is my attack key 
helps a lot
Oh I have the same mouse. I move around with WASD, though and I use Mouse Mode which turns the left click into auto attack, I’ve then got all the abilities bound to all the buttons on the left side.
Yeah i use mouse mode too. But sometimes its hard to left click enemies so thats why i also have attack on middle mouse
I’m using Logitech software as well to rebind my Mouse3 to Z/attack, works pretty well.
