Sorry but I really don't have sympathy for you for these reasons, plasmas and video games have not been the best combos for a long time now because of issues like these and I get that plasmas are better picture for lower price but they are not good for gaming because a lot of games have images in one place for long periods of time that can do that to your screen. Even if you didn't know this, how you didn't notice that before it got that bad is beyond me since I have known people who have had plasmas and played video games on it and they noticed it before it got as bad what you have. Also, it isn't bungie's responsibility to make sure their game is plasma tv friendly, though it would be good for PR, it is your job as a consumer to make sure that the game won't cause burn in on your tv.
