Sorry dude, but you need to do a bit more research on current plasmas before making generalizations like this. Is playing for 2-3 hours a day, 4-5 days a week much? Someone that's not a gamer might say so, but any regular gamer would say not. Do you even own a recent model 2011 or 2012 plasma TV? Do some simple google searches, and you'll find image retention from bright logos, not just gaming HUDs, are a problem with recent Panasonic plasmas. Not just this game but many others with bright HUD sections.
From my experience so far, it appears to be the searing white static images in HUDs with the most IR effect, at least on my 2012 plasma. Like the bright white border around the shield bar in Halo 4, that is what caused heavy IR on mine, and this is after proper panel aging steps and running modest contrast and brightness settings.
