PanzerAzelSaturn: I too searched for the often standard option to switch this setting and found nothing. I'm completely confused why they would change so much about the basic controls and interface of the game when it's likely that the majority of people who pre-ordered and supported their efforts are huge fans of the series who are currently trying to remap their brains to try not to play as if they are playing a new version of an old favorite. I keep moving units around when trying to deselect them and cancelling my spells and other actions by clicking on them, you know, with the button you normally click to do things, the left one! How hard would it have been to add an option for switching right and left mouse buttons for certain interactions? I find it very counter-intuitive and the lack of configuration is especially annoying in a full priced retail release.
