one of the things i would like them to change is the hit box sizes, when i go to face a demon whether there big or small, i cant seem to click away from them. even if i try to start running away from sooo much damage taken, it seems my guy still wants to attack even if my cursor isnt on the demon. so therefore instead of getting to safety, i die terribly. i wouldnt mind if blizz would change the hit box size or make wasd work, thanks
WASD will never and should never happen. Google to read many developer statements as to why it will never happen in this game.
As for dying because you tried to walk away but kept attacking instead, as somebody above said, bind a key to force movement. It's in your options and it's unbound by start. I use "x" since it's where my thumb naturally rests when my ring finger is on tab for the map and middle and index finger are on 1 and 2 for most-used spells. If you bind shift to force attack your thumb can very easily between the two.
But that's just what I use - find something that works and these sorts of deaths will be a thing of the past.
