Playerbase doesn't = $$$. The 11% might not have spent a penny on the game. I doubt they are worrying in the slightest.
nope that's exactly what a larger playerbase brings... more income. your logic couldn't be more flawed. you think that patch was a coincidence trying to shuffle the game like that? they even brought it out only 3 days after testing. If this trend continues Valve will go into panic mode and probably harm the game.
