Nobody said it was dead on accurate but it most certainly shows trends, that is if counting the numbers in the arena today and remembering what they used to be years ago, isnt enough. And a Apr MWA K/D count of over 80,000 in 2008 compared to a 2014 MWA of about 13,000 shows a further "trend". The loss might be even more then 62%.
EWA was roughly 18,000 in 2008 and was about 1,200 in 2014. The "trend" is clear enough.
