@Elessaria666: 99% of 3rd person games use right mouse to rotate camera. Larian is being contrary for the sake of being contrary, not for the sake of improving interface.
I mean, it isn't but that's kinda besides the point. I completely agree middle mouse was a really odd choice to bind it to, but I guess you can't default keybind side buttons until literally every mouse you can buy has one, and we aren't there quite yet.
It is, however, FAR more intuitive to use that than right click, whilst maintaining the fact that we have been right clicking to access extended drop down menu functions since, like, Windows 3.1.
