Wow after playing patch13 1st thing you notice is the 1st skill you get is lock to left mouse button and your unable to change it until level3.
I for one do not like using skill on my left click while playing Diablo it just makes things messy e.g: clicking to move and instead attacking with a skill your forced to use on the key. And yes I did notice that blizzard has added a move key binding in game but that is just a pain when you move with a key then left click to use your skill and if you’re not targeting a unit you move again if you’re not holding shift down.
Blizzard needs to add another button to the skill bar so we can leave left click blank and keep it just as a movement/interact key and not an attack key.
By leavening left click as is blizzard is forcing people to use left click as the main attack key if your build uses more utility skills things that can’t be used in left click atm. And that forces you to use your attack in left click. And as I said before that just make thing a pain since left click is the move key and using a key-binding is just a pain.
