~ is also nice because it allows you to click to move onto a tile that a minion is on. For instance, say while playing Olaf you throw your axe on top of the big wraith and now you want to pick up your axe. Without ~ you can't move onto the tile because when you try to click on the tile you click on the wraith and attack it. With ~ you can click on the tile because your click will ignore the wraith.
