Movement and attacking must be possible to bind to different keys! I could find one blue post on this topic here: http://us.battle.net/d3/en/forum/topic/4662316885?page=15#290 Notice the main topic of the thread is WASD controls there, but that's not at all what I'm talking about. Currently, similar to Diablo 2 (but worse due to larger monster hitboxes), when you try to move but accidentally click near a monster, you will move to that monster and attack it with your "primary"/"left mouse" attack instead. The only real solution to this is to allow us to disable any attacking done by left mouse button so that it is used for movement only. Currently there is a "move" button that you can bind, but since you can't bind primary attack to anything other than left mouse button, it doesn't help, unless you want to move purely with the keyboard, which I find quite awkward. We basically need to be able to bind the left and right mouse button attacks to whatever keys we want! As seen in the blue post, that's something they're actually considering, so it would probably help if anyone with US forum access would contribute into bringing it to Blizzard's attention that this is actually important for many serious gamers who don't want to die because they accidentally clicked the huge monster's hitbox and attacked it instead of moved away to save their life.
