This is a long standing pet peeve of mine, but as a warlock: the floaty, weird chase cam style 3rd person view is actually detrimental to some abilities. For example, when using Chaos Reach, if my character drifts even slightly to the right, i lose all visibility of the centre of the crosshair. Whether this is due to the chaos reach beam itself, or due to my fat warlock, it impedes the ability to see what im aiming at.
