Guild Wars 2

What the title says. I would love to map my auto attack to my mouses left button when I’m holding down the right click.

Here is a trivial AutoHotKey script that does just that : when the right mouse button is pressed, the left mouse button performs an auto-attack. This can be used as a workaround for the lack of default autoattack on engineer kits and environment bundles.

Be advised that it (obviously) relies on third-party software, so use it at your own risk. However I do believe that it does not provide an unfair advantage, thus following Mark Katzbach guidelines on the subject of controller profiles.
