So I just discovered the functionality for action cam in wow. It’s pretty funny. It basically gives you a funny overview of things.
There are two modes of ActionCam, both which slightly changes based on how far you are zoomed out on your character. When doing full ActionCam mode and zooming in for first-person view, your running, rolls, melee abilities, etc, makes your camera movement enhanced.
For the cam-mode to engage, you need to target something. Try targetting a dummy, mob or do a duell.
Full ActionCam mode:
/console actioncam full
Basic ActionCam mode (This one is really funny as healer in BG’s; especially disc in my opinion):
/console actioncam basic
Turn actioncam off:
/console actioncam off
