I won't argue with anything you said, it's all just opinion.
But, I'm curious. Why does everybody here who complains, think that quoting a meaningless KDR seem to think it somehow justifies their complaint? Ironically, I think having a high KDR actually undermines complaints. If you said the lag was terrible, you can't get a kill, and have a KDR of 0.4 as result then I'd have more sympathy.
