Were you rotating the camera with the left mouse-click or right mouse-click, pretty sure we were all meant to rotate with the right-mouse click because it provided a smooth rotation that you could control, and with the right-click button it didnt lock the camera with you or "instantly move with you", that however did occur with the left mouse click.
Oh yea, people have to remember that you use the RMB to rotate the camera in GW2, A + D / Q + E are for moving your character, not the camera.
