Been playing some other MMOs lately and the Action Cam is making a comeback imo. Either that or its just a me thing. Guild Wars 2, World of Warcraft, Elder Scrolls, New World all have some sort of action cam implementation.

GW2 and Wow are both opt in features, with GW2 being the better imo

ESO and NW are action cam by default with little to no other options for standard camera and interaction.

FFXIV has it too! Default ctrl+f or clicking in on the right analog stick on controller. That's the downside, is it is locked to you needing a target and also hampers your movement speed as it's actually a Lock-On and not an Action-Cam, but is so dang close it makes me wish and wonder if SE could implement something to have a better experience with the lock-on feature or the camera in and out of combat as a whole.
