I role combat spec, and need three more champion gear pieces. I usually finish matches with highest damage, and the screenshot below is the highest damage I've achieved so far, just yesterday in fact. I'm slowly creeping towards the 500k mark, and I believe with a good healer with you it could easily be achieved, I'm sure some Sentinels have it already. I was in a premade team in this screenshot,and although the opposition were mainly made of 50's, they were a really poor team in general. http://i40.tinypic.com/25rzia9.jpg
