Actually you've only helped my point with each post you make, proving once again that inflated AOE damage numbers are meaningless, that screenshots are telltale and seldom reliable, and that there are many factors that go into how the numbers get achieved. It's killing blows, not damage, that matters in PVP. Doing 700k+ damage and killing no one does nothing for your team other than pad your own score (and their healers), and becomes much easier when you never die... let's see that in instant replay!
You mean this one?
Or this one?
And.... crit. Killing Blow.
