Why not have right click function the same as left click on the campaign layer? That way people can just default to right click if they want a consistent button? Everywhere else in the game (intel and regular map, tactical map, market, colony management, etc.) LMB selects things and right click is laying in a course or a battle waypoint. It's just the campaign layer where movement becomes the primary action and jumps from RMB to LMB, and RMB becomes free look. That's what's weird. Free look should be on a hotkey or in the menu and in the campaign layer both mouse buttons can be movement, so people can just get used to RMB to lay in a destination on any point, just like the map, while LMB can be movement that doesn't override the currently laid-in destination. So it's a primary form of movement, an "I want to control my movement closely, and particularly, right now" while RMB remains a higher-level, less-used "I want to pick a destination" button.
