if you run into the camera with the action camera on and hit about face you back backwards for a few seconds.
if you are running with the camera you turn about face with out walking backwards
If you are using the free camera you turn about face normally
If you run into the camera with the action camera on and cast a skill that does not require you to face that direction, you character walks in that direction and faces that direction
If you have the action camera on you can run into the camera and cast behind you
The aminations for doing these things seem like they could just be removed to make your character function as expected, just make the character cast on the spot you have selected when running into the camera with free camera on and do not force and back walk when you hit about face
