Unlocked camera is way too hard for me so I just gave it up. I have played all sorts of other types of games, shooters, RPGs, Sports, action, racing, and I can't think of any other game I have played that requires being completely on top of the action in an area while moving the camera around. It doesn't help that the main way to move your character, by mouse, is also the same way you have to control the camera. To me, playing with unlocked camera is as unintuitive as it would be to play a sports game from a FPS perspective.
Knowing what to do in this game doesn't limit me nearly as much as actually being able to do it. Adding one more thing to monkey with only takes something away from some other area of play. If, however, you are able to easily manage the action and reaction aspect of the game well enough already, then give unlocked a shot.
Actually, just writing this makes me think how awkward the entire control and view schemes are for this game. Mouse controlled character movement in a game that requires character actions at least as precise as in an MMORPG is really an odd choice
