When I play single player, and sometimes on multiplayer the camera gets messed up. I'll be playing and after a while in single player I'll be far away from where my tori was standing in the beginning of the match. Then when I want to get the camera to him it becomes so sensitive; I'll be moving the camera slightly to the right and it moves like crazy. It becomes annoying. I know I can press 2 to change the style of the camera, but I prefer the regular camera style. So maybe some how by clicking on a spot while pressing a specific key we can make it that the spot that was selected will be the new area that the camera revolves around. I think it would be very helpful.

Were you using the right click and drag on the mouse or WASD? because using WASD is usually a bit more accurate I find then the right click drag.
Also I disagree with this idea I just don't see any point in it the camera isn't that hard to use and I don't think it needs any changes
